About StatTools

StatTools gives Microsoft Excel - the industry-standard data analysis and modeling tool - a new, powerful statistics toolset! StatTools is a Microsoft Excel statistics add-in, enabling you to analyze data in Excel worksheets and work in the familiar Microsoft Office environment. By combining a powerful data manager, along with analyses that rival the best statistics packages available, StatTools brings you the best of two worlds: Microsoft Office ease-of-use and reporting, and robust statistical power.

StatTools covers commonly used statistical procedures, and offers the capability to add new, custom analyses to Microsoft Excel. The accuracy of Excel’s built-in statistics calculations has often been questioned, so StatTools doesn’t use them. All StatTools functions are true Excel functions, and behave exactly as native Excel functions do. Over 30 wide-ranging statistical procedures plus 9 built-in data utilities include forecasts, time series, descriptive statistics, normality tests, group comparisons, correlation, regression analysis, quality control, nonparametric tests, and more.
