Stats.xls is an Excel workbook for doing basic statistics calculations and charting at the level of a typical introductory course. It has been most recently updated on 11/9/2017


If you can open an Excel spreadsheet on your computer, then you can immediately use Stats.xls. It is an ordinary Excel file; it is not an add-in; no macros are used; no "installation" is required. It works on stand-alone and networked PCs and Macs (dating back to Excel versions circa 2003).


Stats.xls should be easier to use than most statistics packages or Excel add-ins for statistics. With Stats.xls, you simply enter your raw data or summary statistics directly into the specified cells and all calculations and charts are instantly displayed. There is no need to navigate a menu structure. Instructions appear on each worksheet.


Unlike most stats packages, you can customize Stats.xls to your heart's content.


Stats.xls is free to individual users. All others, please contact the author.
