Data Management: This group allows you to manipulate your data set in various ways, either by rearranging the data or by creating new variables. These operations are typically performed before running a statistical analysis. Summary Analyses: This group allows you to calculate several numerical summary measures for single variables or pairs of variables. Tests for Normality: Because so many statistical procedures assume that a set of data are normally distributed, it is useful to have methods for checking this assumption.
Regression Analysis: For each of these analyses, the following outputs are given: summary measures of each regression equation run, an ANOVA table for each regression, and a table of estimated regression coefficients and other statistics. In addition, StatTools gives you the option of creating two new variables: the fitted values and residuals.

Plus, you can create a number of diagnostic scatterplots. Quality Control Charts: This set of procedures produces control charts that allow you to see whether a process is in statistical control. Each of the procedures takes time series data and plots them in a control chart. This allows you to see whether the data stay within the control limits on the chart. You can also tell if other nonrandom behavior is present, such as long runs above or below the centerline.
Each of these procedures provides the option of using all the data or only part of the data for constructing the chart. Furthermore, each lets you base the control limits on the given data or on limits from previous data.
Nonparametric Tests: Nonparametric tests are statistical procedures which can be used to make successful inferences when there is little available data. They are more robust than many of the widely known parametric hypothesis tests. Nonparametric tests do not always need the parametric assumptions—such as normality—or generalized assumptions regarding the underlying distribution. In most cases, the nonparametric tests are much easier to apply and provide clearer interpretation than traditional parametric tests.
StatTools is a true add-in to Microsoft Excel, integrating completely with your spreadsheet.
Data Analysis Using Excel
Browse, define, analyze — while never leaving Excel. DLLs, not macro calculations. StatTools comes in Professional and Industrial editions. With Expanded Data Sets, you can define variables that span multiple worksheets. The Professional edition allows 10, data points for a single variable. StatTools is fully compatible with all DecisionTools programs and can be combined with them for greater insight and analysis.
For example:. You can also apply RISK functions to StatTools time-series forecast results to simulate possible outcomes with more precision than the times-series analysis alone. The best analyses at a great price—with the DecisionTools Suite.
StatTools is available through a variety of licensing options, including corporate, network, and academic licenses. Training, consulting, and books can be bundled with your software to ensure you and your staff get the most out of your investment. With your StatTools purchase, you should also consider a copy of Learning Statistics with StatTools, a practical, straightforward guide to getting the most out of StatTools and statistics generally.
How to use statplus in excel mac
Much more than a software manual, this book shows you how to apply statistics to a variety of real-world problems. Each chapter discusses a set of statistical procedures, grouped as they are in the StatTools menu structure.
Example models are also included that you can customize for your own needs. Palisade does not attempt to rewrite Excel in an external recalculator to gain speed. Asingle recalculation from an unsupported or poorly reproduced macro or function can dramatically change your results. Where will it occur, and when? Get accurate results using StatTools! This allows for vastly larger models and greater computational power. Palisade Brochure. Buy Now. Free Trial Download. I've worked with Minitab before, and now abandoned it altogether since StatTools is so much better!
List of StatTools Analyses. I applaud StatTools' powerful statistical analysis. Predictably, similar formulas in the range D3:D7 calculate the squared differences for the other slot machine symbols.
Excel Data Analysis For Dummies, 2nd Edition
Very suspicious. RT function but calculates the left-tailed probability of a chi-squared distribution. RT function returns the inverse of the right-tailed probability of a chi-square distribution. RT function, refer to the worksheet fragment. With six possible outcomes on the slot machine, you have five degrees of freedom.
This function returns the value Note that D10 is used as the first probability argument because that cell holds the level of significance calculated by the CHISQ. DIST function. INV function returns left-tailed probability of a chi-square distribution. The chi-square test function lets you assess whether differences between the observed and expected values represent chance, or sampling error.
Again referring to the example of the suspicious slot machine, you could perform a chi-square test by entering the following formula into cell D14 and then comparing what you observe with what you expect:. The function returns the p-value, or probability, shown in cell D14, indicating that only a 1. TEST function returns — to a level of significance.
