Stats Wiki

The Stats Wiki is a free online statistics textbook. It includes chapters on a wide variety of statistics as well as Microsoft Excel and SAS code examples so that you can run the analyses yourself.

Construction of the Wiki is still underway. Planned topics include z- and t-tests, Pearson and Spearman correlation, simple and multiple regression, and univariate and multivariate varieties of the Analysis of Variance (ANOVA) procedure. I also plan to include material on planned comparisons and post hoc testing. Stay tuned for plenty of updates!

The table of contents is listed in the navigation menu to the left. Click on the link that you need, or click on the Introduction link to read from the beginning. You can also search by keyword using the search box.
