Why Fibre Optic Technology Is Faster Than Copper

The fiber optic technology operates the vibrations of light to hold up the information and evidence along with the threads of plastic or cup. The optic fiber can hold up the elevated regularity varies, while the copper wire forfeits the signal courage at the elevated regularities.

The fiber optic information or data relationship can transport additional data at elevated lengthier extents than the copper wire. The main benefit of fiber optic cable is that they are eligible for bringing warnings extensively sooner than copper ones.

The regional area can use the system utilizing modern copper cables that can hold up to 3000 telephone phones at one time. And an identical policy utilizing fiber optics can hold up other than 31,000.

The conventional copper wire can communicate the electrical tides, while the fiber optic technology brings the vibrations of light which is produced by a light-emitting diode or beam along with the optic fibers. In this path, it can be distinguished whether there is a difference in power and through this, the data can be encoded.

The fiber optic cables can communicate the data rapidly than the copper wires, as they employ radiant rather than electrical pulses to hold up data from one question to another.

The light can wander a lot quicker than the copper wires or cords in a short period. Also, the light can keep in touch or transmit the warnings powerful as they drift from edge A to edge B. This is not only the lawsuit with the electrical pulses delivered through copper wires.

At the moment, the copper wires bring electrical pulses to the final destination, they are often weakened. This is the explanation for establishing the internet relationship with the fiber optic.

What Are The Advantages Of Copper Cable?

  1. The hardware store bears up the copper cable in a mixture of forms and sizes.
  2. With the usage of copper wire in residences, it is limited inclined to go around and fix it quickly. Additional equipment is utilized to wire the aspects, occasionally it can forfeit the friendship where they are related and become detached.
  3. Copper wire has a lofty melting point, but if the person is concerned about insurance, the copper cable might be one of the decent choices. If an abundance arrives within the cable, it is not likely to scorch or melt.
  4. Copper cable is a smoother or delicate metal. That implies that rather of its strength it can be constructed by fulfilling all the restrictions. The flexibility of the wire gives rise to it differently, for commerce with home wiring and other purposes.
  5. Leaning a copper wire or wire of the appropriate consistency takes a little more than manually bending with the use of the hand. There is no desire or regulation for any other equipment.
  6. The best conductor from all the numerous metals and the cable, copper is the best conductor from all the others.
  7. A strong and influential piece of copper wire can be fulfilled for fulfilling the regulations.

What Are The Advantages Of Fiber Optic Cable?

Fiber optic cable
  1. The fiber optic cable does not contain any electrical interference as different types of cables can not interact or take up the environmental noise.
  2. The fiber optic cannot be affected by electrical interference. This makes it valuable in locations where high voltage or lightning is frequently present there.
  3. The proliferation and lower prices of media converters are giving rise to copper to fiber migration much simpler. The converters furnish seamlessly links that enable the utilization of the existing hardware.
  4. The optics provide incredibly credible transmission of data. It is fully immune to the many environmental factors that affect the copper cable.
  5. The core is made of glass, which is an insulator, and no electric flow can go through. Fiber optic is less vulnerable to temperature instabilities than copper can be immersed in the water.
  6. The fiber optic experience has low and very little data loss even for covering over long distances. As the light travels by the fiber without experiencing casualty of emphasis over time.
  7. The fiber optical cables contribute and distribute more secure communication because it is highly resistant to tapping, jamming, and radiofrequency.
  8. It has greater bandwidth than the copper wire. Also, it has standardized performance up to 10 Gbps. When it’s not currently standard, the speeds can become a reality in the coming near future.
  9. The fiber velocities are dependent on the type of cable used. The single-mode fiber optic cables utilize and offer greater and several which is 62.5 or 50 multimode cables.
  10. The multimode cable fiber is an optical fiber that is largely utilized for communication through short extents within a campus.
  11. The multi-mode connections can be utilized for data rates up to 100 Gbits.

Why Fibre Optic Cable Is Better And Faster Than Copper?

  • The fiber optical carries higher frequency ranges. At the higher frequencies, the copper cables lose the signal capabilities or strength.
  • The fiber optic is scarcely influenced by electromagnetic interference and noise. The data can be transferred over two hundred kilometers without any loss of quality.
  • The cooper cable signals will lose or degrade over large distances.
  • Copper is cheaper than fiber optical because it is already installed in the buildings. The copper wire or cable can be used in desktop, wiring closets, and small applications. But fiber optic cable is used in between buildings, in between floors of the buildings, and in interconnecting equipment.
  • The fiber optical cables have lightweight, non-flammable, resists corrosion, can last up to thirty years, and have one hundred to two hundred pound tension units.
  • The fiber optic cables are narrow, which measures similar to human hair. They transmit an incredible amount of data.
  • The fiber optic cables required a covering, which is at least two millimeters in width.
  • The light emission in the fiber optic cables does not have or produce any EMI, thus the fiber is more comfortable, boosts the ROI, and requires less communication.
  • Fiber optic cable carries light pulses along with flexible glass thread but the copper wire carries electrical wires.

Top 8 Security Issues in Cloud Computing

More than 70 percent of companies worldwide are now operating on the cloud – at least partly – and according to Cloud Security Alliance.

70% is no big surprise with advantages, such as reduced fixed costs, more significant flexible operation, improved cooperation, updated software, and freedom to operate from anywhere.

However, there are security concerns in the cloud.

“90% of organizations are really or moderately concerned with public cloud safety,” the latest “Cloud Protection Spotlight Study,” shows the range of issues ranging from sensitivity to hijacked accounts to insider threats to complete privacy violations.

Although cloud providers are beginning to store and share data in a new era, many businesses are either reluctant or are moving on without a specific safety plan.

We will present a broad image of the top 8 cloud-based security issues that you should know about.

Data Breaches

Cloud storage and services were relatively recent, but data breaches of all types have existed for many years. The question remains: “With sensitive information becoming stored digitally instead of on-premises, is the cloud necessarily less safe?”

A study even by “Man In Cloud Attack” Ponemon Institute reported that more than 50% of the IT & security professionals surveyed felt that perhaps the security steps their company has taken to protect cloud data are low. This research utilized nine cases in which there had been a data breach to decide if this belief was also, in fact, established.

After analyzing every situation, the study concluded that the average data breach is three times higher than for cloud-using companies. The easy result would be that the cloud has a special collection of features that render it much more vulnerable.

Accounts Hijacking 

The development and deployment of the cloud have up a new range of account deprivation problems in several organizations.

Attackers are now able to access confidential data stored on the cloud remotely by using the username; attackers could also falsify & interpret information via hijacked credentials.

Scripting glitches and repeated codes often provide hijacking, making it easy for hackers to access credentials without detection. Amazon encountered a cross-site programming flaw in April 2010, which also targeted consumer credentials. Many threats are related, including keylogging, phishing, & buffer overflow. The latest threat – known as the Man In Cloud Attack – therefore includes theft of user tokens that cloud platforms are using to check individual devices without the need to log in during every upgrade and sync.

Insider Threat

It may not seem likely that your organization will target, and the inside threat exists. Employees may misuse or access information about customer accounts, financial forms as well as other sensitive information by using their authorized access to cloud-based services of a company.

Furthermore, such insiders also must not have malicious intentions.

An Imperva report, “Inside Track on Insider Threats,” finds that the abuse of knowledge via malicious means, incidents, and malware is indeed an insider threat. The survey also explored four best practices organizations that should pursue, including access management, priority strategies, technology implementation, and strategic alliances, to execute a safe strategy.

Malware Injection

These were scripts or codes embedded in cloud services, acting as “true instances.” It implies which malicious code could be inserted into another cloud system and could be used in the cloud application program or service.

Because once the cloud starts running only with injection, attackers will wake up, jeopardize the security of confidential information and steal data. The East Carolina University report examines the threats posed by malware injectors on cloud computers and states that perhaps the “malware attacks are becoming an important safety concern for cloud computing.” 

Cloud Services Abuse

The extension of cloud service facilitates the hosting of large volumes of data for small and company-based entities. Even so, cloud computing capacity that never happened before, however, has made hosting and spreading malware, illicit apps, as well as other digital properties easier for hackers as well as registered users.

In some situations, both the cloud service provider, as well as its customer suffer from this activity. For instance, privileged users may raise security risks directly or indirectly and violate the service provider’s terms of using it.

These threats also include sharing pirated software, images, music, and books, with legal implications for penalties and settlements of up to 250000 USD under American copyright law. Such fines could be even more prohibitive, depending on the damage. By tracking use and setting rules on your staff host throughout the cloud, you will reduce the risk exposure. Service providers and legal bodies, including such CSA, have described abuse or misconduct along with detection methods.

Insecure APIs

Users have the ability to configure their cloud experience with Application Programming Interfaces.

However, because of its very existence, APIs can threaten cloud protection. They not just enable businesses to customize the functionality of their cloud services to meet business needs; they even authenticate, access, encrypt effects.

As API infrastructure expands, its security risks are also improved. APIs offer programmers the tools to develop their applications with much other software that is vital to their work. YouTube is a common and straightforward example of an API, where developers can incorporate Youtube videos into their websites or apps.

User communication between applications is the weakness of an API. Even though it can benefit programmers and companies, it also leaves exploitable safety risks.

Service Attacks Denial

In contrast to other types of cyberattacks that are usually started to detect sensitive information in the long term, denial of service attacks will not break the security perimeter. Instead, they try to prevent legitimate users from accessing the website & servers. Even so, in certain situations, DoS is often used as a screen for many other malicious activities as well as for taking security devices, including firewalls for web applications.

Inadequate Due Diligence

While most of the problems we examined are just technical in nature, there’s no concrete strategy for an enterprise for its objectives, cloud policy, and personnel, but this specific security gap exists. It’s the human element, in other words.

Furthermore, inadequate due diligence would pose a safety risk if an enterprise migrates rapidly to a cloud without adequate expectations of the services.

For businesses whose data is controlled by PII, PHI, PCI, and FERPA, or those that manage financial data for consumers, that’s also incredibly relevant.

So these are some of the great security issues that you can notice in cloud computing. So be aware of them before using any tool to prevent yourself from any loss or damage.

How Space Technology Benefits the Earth

Space technology is a tremendous advantage to just the world, particularly in communications, positioning services, Earth monitoring, including economic activity in relation to space programs financed by government funding. Since the launch of Sputnik in 1957, humanity’s outer space capacity has expanded significantly. But since, we’ve seen people landing mostly on the Moon, 135 space shuttle flights, ISS building & launch of over 8100 spacecraft, including scores of explored missions at every corner of its Solar System. In 2024, the United States proposed an accelerated timetable for people to return to the Moon forever. A return to just the Moon is also based on several other nations. The worldwide commercial space capacities are fast expanding far beyond the space sector, which has taken in much more than 277 billion USD during last year’s over 2,000 space companies – like construction communications orbital launch vehicles, satellites, orbital habitats, Moon & mars rovers, space production platforms & space greenhouses.

One explanation for this latest space-related explosion seems to be the falling cost of launch to low Earth’s orbit. Throughout the previous, the LEO launch was one of the most costly parts of every space effort. The estimated costs of over 10000 USD per kilogram of launched mass have traditionally been more significant. In recent times, Blue Origin, SpaceX, ULA, and other space companies effectively followed reusable start-up vehicle technology, promising to dramatically reduce LEO start-up costs. Now the lowest cost throughout the industry is SpaceX’s Falcon Heavy with such a base price of 1655 USD per kilo. LEO. SpaceX and many others’ long-term goals are to reduce this cost to it or less $100 per kg. This low cost of launch would significantly alter the economy of several space models, making a new age of ability previously considered prohibitively costly.

Other developments, including the manufacture of space-based materials from resources mostly on Mars, on the Moon, or asteroids, will further boost the economics of spatial activity by significantly reducing the volume and, therefore, costs of Earth material. A significant example is the extraction of rocket propellants in space from water-rich Moon regions or asteroids, which might reduce transportation costs in places beyond LEO.

Space Activities Which Impacted Positively 

Observation of Earth for climate monitoring:

Accurate space system weather predictions are becoming a significant factor of everyday life that affects government, business, and personal decision-making. Weather satellites almost definitely save thousands of lives each year through public warnings of the storm. Nobody can describe immediately how many lives have been held each year, but in 1900 there were 6000-12000 people killed by a hurricane in Galveston, Texas, since they did not have any warning.

Satellite earth observation also monitors greenhouse gasses and some other leading climatic indicators, and even the overall health of the Earth ecosystem. Without such satellite-based environmental knowledge, climate change strategies will have a less scientific base.

Observation of Earth Resources:

Earth monitoring system provides agricultural production, management, and management information, freshwater management including forest management, management of fish, and monitors harmful activities, including illegal deforestation, burning, wild animal breeding, and environmentally destructive mining.

Communication Services Based on Space: 

Capacities of space communication affect every other aspect of human society favorably. Satellite technology has revolutionized the banking and financial affairs and navigation as well as daily connectivity, allowing for full regular international and long-range domestic phone calls, streams, video streaming, and radio and satellite TV.

Space-based Navigation, Positioning, and Timing Services 

Increasing water and land navigation, logistics, like rides that turn personal transport, military operations, precision agriculture, electricity grids, and several other industrial or societal aspects of its Earth’s lives, has become the basis for global satellite PNT systems, which might locate within just a few meters (or much more) anywhere else on the Earth. Space-based mobile location technologies used only by mobile telephone applications from maps to match-and-trade services are so entangled with everyday life that their sudden termination is regarded as disastrous.

Expanding Economic Possibilities in Developing Commercial Non-space and Space Sectors

In addition to long-term satellite services, our growing space industry is bringing economic opportunities not just to those directly employed in the space industry and non-space stakeholders, including several small companies, by moving beyond exclusive reliance on restricted government budgets or cost-plus contracts. Furthermore, a growing commercial space industry not just leads to high-tech employment, but rather to daily jobs linked to manufacturing, food, wholesale and retail, finance as well as in the entire community, where commercial space enterprises are located.

STEAM Education

In addition to the economy, a healthy space sector will continue to encourage young and old to learn about new borders, findings, and innovations and promote STEAM disciplines, helping to build a scientifically informed community that would be able to participate in an ever-growing world powered by technologies.

Countering Geopolitical Problems

The only other positive strength, sometimes against mutual suspicion & geopolitical rivalries, is joint space projects amongst nations. The ISS is an important example of even a project of this nature and a source of pride for all participating countries. The same aim is also achieved in cross-border business-business ties. We are really a global society and are much more interrelated and intertwined, both public and private.

Space Spinoffs 

And over 2000 instances of space-developed inventions have been available on Earth, but since the dawn of its space program, like wireless power instruments, firefighter devices, freezing-dried food, integrated circuitry, enhancements to kidney dialysis, lightweight isolation, lightning & automatic credit card transactions. There are more than 2000 instances. NASA annually monitors spinoffs along with a broad range of topics, including transport, consumer products, public safety, electricity, and the atmosphere, industrial efficiency, IT, & medicine, and health. The medical problems of isolated communities in deep spaces would probably lead to future healthcare spinoffs.

So these were some of the most important benefits of space technology which has impacted the Earth and its people positively and opened a way to new sources of information. You must remember that in the future these technologies will bring a lot of positive effects for the Earth which will be very beneficial.

10 Amazing and Weird technologies that’ll change the world in the next few decades

Remember the old days when there were limited technologies. People were unknown to even the most common technologies nowadays such as computers, mobile phones, and laptops. However, with changing times there were several inventions in the field of technology. Now, we are living in a world where we have the complete assistance of science and technology. Technology has advanced to such an extent that almost anything can be done with the help of technological equipment.

There is no limit to creativity and innovations, even in today’s new inventions are being made. The technologies have made our lives much easier and are still in the process. The most powerful thing in the world today is technology, people have become partially dependent upon the technologies. It has the power to complete even the most complex tasks easily.

Some of the weird yet amazing technologies will completely change your way of living and will also create a new world to live in with highly advanced movies.

  1. Robots will make your tasks easier and interesting

Many of you have seen robots in movies, however, very few have witnessed the robots in real life. The scientists of NASA have created several robots of distinct shapes and sizes. Being a technological creation these robots do not require oxygen or food and water to eat. All they need is an adequate charge and a specific set of data.

These robots can also be used in the workplace and can relieve much of your workload. All the dull and monotonous tasks which you complete in hours, these robots can complete in just a few minutes. There will a greater work efficiency and almost few to no mistakes.

  1. Self-driven cars can take you to effortless long drives

Many of you love long drives but often find it tedious and for the ones who do not know driving is a dream. But it won’t be with self-driven cars which are mainly run by electricity. There are a few such cars on the road however, it hasn’t become much possible. Long-lasting batteries are used in cars and there are charging stations where you can easily charge your car.

Sounds interesting, isn’t it? Well traveling from one place to another in an extraordinary vehicle will be exciting and altogether a different experience.

  1. Escape the traffic with the flying cars

Don’t you feel helpless when you have to reach a place immediately and you are stuck in the traffic? Well in that case the flying cars will be your ultimate rescue. Although there is not a single model of flying cars at present, it is likely to be seen in the future. An innovative idea that will transform your life. Several designs have been made of the cars, the only the implementation is left.

  1. Eco-friendly solar panel technology

Looking into the severe effects of the distinct technologies, using solar panel technologies will not only be safe for the environment but would also prove to be more productive. Although in some industries the solar panel technologies are used, it is not completely in use. With the advancement in technologies, these solar panel technologies can not only be hidden under the tiles but in some places, it is also hidden in the roofs.

Some organizations are also making efforts to hide the solar technology in the roofs of the cars. This will altogether be a different and unique innovation.

  1. Visual Reality will take you into a different world

The concept of virtual reality has so far gained a lot of popularity. People are now enjoying the concept of augmented reality, which is completely fictitious but gives a real-life experience to the users. However, the companies are now trying to implement this concept of augmented reality and virtual reality in their work. In the future, it can be used for visual representations or virtual meetings.

  1. Travel faster with the hyper-fast trains

The hyper-fast trains can run even underground, or underwater. These trains travel at a great speed and will help you reach any of the places in almost no time. Travelling from one country to the other is similar to travelling from one town to another with these hyperfast trains.

  1. Do your work comfortably with the wearable screens

With the advancement in technologies, the large telephones were converted into small screen mobile phones and shortly even these mobile phones will be abandoned and only wearable screens will be used. These screens will be operated from your skin, therefore all you would have to do is implant the screen or wear it on your skin.

  1. Enjoy the 3D printed food in distinct ways

Well, the monotonous and dull-looking food will be presented in a new way through. Just like the papers are printed you can also print the food through 3D technology. If you wish to eat your favourite meal all you need to do is print the food and have it instantly. Exciting isn’t it? Efforts are being made by various companies to adapt to the 3D printing of food items.

  1. Toothbrushes will send the data instantly to your dentist

A simple toothbrush can be used as a data transmitter for the dentist, weird isn’t it? Well in the future it won’t be weird rather would be the most effective. These smart toothbrushes will ensure that you are correctly brushing the teeth. It will scan the condition of your teeth if there is any cavity or plaque in your teeth and conveys it to the dentist.

  1. Intelligent mirrors will give you the health reports

Again a weird thing to hear, how can a mirror scan the health problems within you. Well, it will in the future. The smart mirrors will scan the various health problems you are undergoing. It will warn you about the various deficiencies in the body.

All the above technologies may appear weird, however, they will change the way you live. The future of technologies is quite bright and will be a boon for the people.

What is this product?

statistiXL 1.8 Released

The final release of statistiXL Version 1.8 is now available. This release is mainly intended to correct some charting layout issues experienced with Excel 2007.

  • statistiXL now provides support for Microsoft Office Excel 2007. This overcomes incompatibilities experienced by Version 1.6, particularly with regards to charting. It also includes the ability to work with the new format larger worksheets of 1048576 rows x 16384 columns.  
  • Version 1.7 of statistiXL now provides support for Microsoft Windows Vista Operating Systems. statistiXL 1.7 will install and run under Microsoft Windows Vista.
  • Support for non-English language versions of Windows and Office has been enhanced. In previous versions of statistiXL, checkbox options on dialog forms were not properly restored between tests. Checkboxes would typically be restored in an indeterminate state (i.e. neither checked or cleared). If not manually corrected for each test this would lead to unexpected errors when attempting to perform an analysis. Checkbox settings are now remembered and restored correctly between tests when running statistiXL on non-English versions of Excel and Windows.
  • The ability to add Prediction Bands to bivariate regression plots has been added. This supplements the Confidence and Standard Error Bands available in previous version of statistiXL.
  • Multiple Linear Regression now tests for Multicollinearity between variables. Variables with a Tolerance of 0, indicating exact multicollinearity, are automatically excluded from the analysis.
  • Cluster Analysis now behaves like other tests, outputing results to a new blank worksheet when the Output Range field is left blank.

statistiXL is an extremely powerful, feature rich data analysis package that runs as an add-in to Microsoft’s popular Excel™ spreadsheet program. It provides access to a wide variety of both parametric and non-parametric data analysis tools and statistical tests. By working from within Microsoft Excel™, statistiXL is able to leverage the existing features of Excel™ and provide a host of additional benefits including:

  • A familiar and powerful user interface for entering and manipulating data
  • A wide variety of formatting options for altering the appearance of results
  • The presence of a sophisticated charting package that allows both the manipulation of charts produced by statistiXL and the manual creation of new charts based on statistiXL‘s output.
  • The ability to perform further ad hoc analysis using Excel’s™ own built-in functions and calculating abilities.

Features

Factor Analysis

Factor Analysis is a procedure that seeks to determine a reduced number of variables, called factors, that explain much of the variation present in a larger number of measured variables. statistiXL provides a comprehensive module for Factor Analysis, with a variety of analytical options. Either the correlation or covariance matrix can be used in calculating the factors. The number of factors to be extracted can be established by several different criteria: 1) the number of factors can be chosen to encompass a specified percentage of the total variance in the original data, 2) you can choose to extract factors with eigenvalues greater than a set value, 3) you can extract a specific number of factors. A variety of methods are included for determining the factors including the principal component method (not to be confused with principal component analysis), principal factor method, and maximum likelihood method. The axes of the resulting factors can then be rotated to improve the factor structure using either Varimax, Quartimax, or Equamax procedures.

Results are presented in tabular form. Descriptive statistics and the correlation or covariance matrix are provided, if these options were selected.

Linear Regression

Linear regression attempts to explain the variation present in one variable (for example Height) in terms in terms of a linear relationship to variation in one or more predictor variables (for example Age). statistiXL provides comprehensive Model I regression analysis. The module allows the selection of one or more predictor variables for each single dependent variable. Options include forward or backwards stepwise regression (with P level to enter or remove), forcing of the relationship through the origin, and graphical output (normal probability plot, residuals plot, scatterplots).

Results from regression analysis are presented in tabular form and graphical form. Summary statistics are provided if this option is selected. Statistics include the R², the correlation coefficient, the adjusted R², and the standard error of the estimate. An ANOVA table is given, to summarise the significance of the regression relationship.

Principal Component Analysis

As with Factor Analysis, Principal Component Analysis is a technique that attempts to reduce complex data sets consisting of many different variables to a smaller set of new variables that still manage to describe much of the variation in the original data. These new variables, called Principal Components, are chosen to be independent and to maximise the variance found in the original data set. statistiXL provides a number of options for Principal Component Analysis. Either the correlation or covariance matrix between variables can be selected as the basis for analysis. All Principal Components can be extracted or a subset of these based on limits such as the number to extract, the percent of variance to explain or the value of an eigenvalue. Screeplots can be produced to help in the visual determination of the appropriate number of Principal Components to extract.

Results are presented in tabular and graphical form. Descriptive statistics and the correlation or covariance matrix are displayed, if these options were selected. The eigenvalues are then tabulated along with the percent of variance and cumulative percent of total variance evident in the original dataset that each of the extracted Principal Components explains.

Analysis of Variance and Covariance

Analysis of Variance (ANOVA) is used to determine whether there is a difference between three or more categorical sets of values. Analysis of Covariance (ANCOVA) on the other hand, while also used to determine whether there is a difference between categorical sets of values also takes into account the effect of one or more numerical variables called covariates. StatistiXL provides both univariate and multivariate ANOVA and ANCOVA. Factors can be specified as fixed or random and the nesting of factors is also supported. Simplified dialog boxes aid the rapid analysis of full factorial andrepeated measures models, while for more advanced analyses a comprehensive dialog box is available that allows custom models to be specified precisely detailing the factors and interactions to be included in the analysis. Post Hoc Tests are provided so that you can drill down into your dataset and see what, if any, the major differences between groups are.

Results are presented in tabulated form, starting optionally with a table of simple descriptive statistics for each group.

Contingency Tables

A contingency table is a table of counts or frequencies. It lists the number of times that each of 2 or more variables falls into a variety of different categories. A contingency test simply examines the null hypothesis that the frequencies of observations found for one variable are independent of the frequencies of observations in the other. statistiXL provides a flexible module for the analysis of contingency tables. Two-way and multi-way contingency tables can be analyzed. The statistics available for the frequency test are Chi² and log-likelihood, the latter being a good alternative approach to Chi² if the expected frequencies are small. Yates’ and Cochran’s corrections for continuity are provided for 2×2 contingency where such an adjustment is recommended because of the low degrees of freedom. statistiXL explains how to subdivide a contingency table and warns of the limited statistical value of this approach. A Heterogeneity Chi² can be used in a contingency table analysis to determine if a number of sets of observed frequency data can be combined into a single set. statistiXL explains how to analyze contingency tables for heterogeneity.

Results are presented in tabulated form, starting with an optional table of a summary of the observed and expected frequencies. The test results are then presented, with the Chi² and Log-likelihood values, along with their degrees of Freedom and P values.

Descriptive Statistics

The descriptive statistics feature of statistiXL provides a quick and easy summary of the basic parametric and nonparametric statistics that describe a sample of values. Unlike many packages, statistiXL provides modules for both linear data and circular descriptive statistics. The descriptive statistics which can be provided (by user selection) with the linear descriptive statistics module are: mean, median, mode, standard error, standard deviation, variance, coefficient of variation, lower and upper confidence limits, 25th and 75th percentiles, sum, minimum and maximum values, nth smallest and largest values (with user input of n), range, count, skewness (with probability if count >9) and kurtosis (with probability if count >19). If these data are sampled at random from anormal distribution, then the data are best summarized by the parametric statistics such as mean, variance and standard deviation. If the data are sampled from a non-normal distribution, then the non-parametric statistics such as median, mode, percentiles and range may be more appropriate statistics for summarizing these data. Options for graphical output includes a “box and whisker” plot and an error bar plot.

A sample of values collected using a circular scale (e.g. time of day or compass bearing) can be described by a variety of descriptive statistics, the more common being the mean angle, angular variance, and angular standard deviation. Optional graphical output includes a circular plot.

Nonparametric Statistics

Nonparametric statistical tests are distribution-independent tests that are used to analyse data for which an underlying distribution (such as the normal distribution) is not assumed. Non-parametric statistics have a number of advantages over parametric statistics.

statistiXL provides a diverse array of nonparametric tests. The sign test can be used to examine whether two populations have the same median, and for observations in pairs with one of each pair coming from each population. Various modifications of the sign test can be used for specific tests The Friedman test for blocked data is equivalent to a sign test, but for more than 2 groups. The Mann-Whitney test (U statistic) is a nonparametric test that uses the ranks of two independent samples, from the highest to lowest (or lowest to highest), to calculate the U statistic; it is the nonparametric analog to the parametric two-sample t-test. The Wilcoxon’s signed-rank test ranks the differences between pairs of data (or single data set of a sample) and compares the sum of positive and negative ranks with a critical U value; it is the nonparametric analog to the parametric paired t-test. The Kruskal-Wallis test is a nonparametric test for the comparison of 3 or more treatment groups, which are independent; it is the nonparametric equivalent to analysis of variance (ANOVA). A common nonparametric correlation test is Spearman’s rho rank correlation coefficients; this is analogous to the parametric Pearson’s correlation coefficient. Mood’s Median Test examines whether two or more samples come from a population having the same median. The Wald-Wolfowitz Runs test analyses a sequence of observations, or compares random samples which are mutually independent, for two or more outcomes e.g. two species of antelope, or three brands of automobile. Results are presented in tabular form.

@Risk for Excel

Excel Ease of Use

RISK is a true add-in to Microsoft Excel, integrating completely with your spreadsheet. Browse, define, analyze—while never leaving Excel. All @RISK functions are true Excel functions, and behave exactly as native Excel functions do. @RISK windows are all linked directly to cells in your spreadsheet, so changes in one place are carried out in the other. @RISK graphs point to their cells via callout windows. Drag-and-drop ease, context-sensitive right-click menus, and the @RISK toolbar make learning and navigating @RISK a snap.

What’s New in @RISK 5.7

@RISK 5.7 is fully compatible with 64-bit Excel 2010. 64-bit technology enables Excel and @RISK to access much more computer memory than ever before. This allows for vastly larger models and greater computational power.

Simulation of Password Protected Sheets
@RISK now allows you to simulate worksheets that have been password protected in Excel. No longer do you need to unprotect your sheets to perform risk analysis, saving you valuable time.

@RISK and RISKOptimizer Merged Ribbon
Because RISKOptimizer is often used to optimize @RISK models, the buttons for RISKOptimizer have been added to the main @RISK ribbon bar in Excel for greater ease of use.

New @RISK VBA Control Methods
The new RiskResultsGraph method of the RiskSimResultsCollection object allows you to make graphs with the same syntax as the RiskResultsGraph Excel function.

What is this product?

@RISK for Six Sigma
@RISK comes with Six Sigma statistics, functions, and reports. It is used to identify, measure, and root out the causes of variability in your production and service processes and designs.

Model, Simulate, Understand

Running an analysis with @RISK involves three simple steps:

1. Set Up Your Model. Start by replacing uncertain values in your spreadsheet with @RISK probability distribution functions, like Normal, Uniform, or over 35 others. These @RISK functions simply represent a range of different possible values that a cell could take instead of limiting it to just one case. Choose your distribution from a graphical gallery, or define distributions using historical data for a given input. Even combine distributions with @RISK’s Compound function. Share specific distribution functions with others using the @RISK Library, or swap out @RISK functions for colleagues who don’t have @RISK.

Next, select your outputs—the “bottom line” cells whose values interest you. This could be potential profits, ROI, insurance claims payout, disease recovery rate, or anything at all.

2. Run the Simulation. Click the Simulate button and watch. @RISK recalculates your spreadsheet model thousands of times. Each time, @RISK samples random values from the @RISK functions you entered, places them in your model, and records the resulting outcome. Explain the process to others by running your simulation in Demo Mode, with graphs and reports updating live as the simulation runs.

3. Understand Your Risks. The result of a simulation is a look at a whole range of possible outcomes, including the probabilities they will occur. Graph your results with histograms, Scatter Plots, cumulative curves, Box Plots, and more. Identify critical factors with Tornado charts and sensitivity analysis. Paste results into Excel, Word, or PowerPoint, or place them in the @RISK Library for other @RISK users. You can even save results and charts right inside your Excel workbook.
@RISK Industries & Applications

@RISK is used to analyze risk and uncertainty in a wide variety of industries. From the financial to the scientific, anyone who faces uncertainty in their quantitative analyses can benefit from @RISK.
