(KnowWare: Denver, CO) -- Microsoft removed the Data Analysis Toolpak from Excel 2011 for the Macintosh in 2008, eliminating statistical tools such as ANOVA, t test, F Test, and regression analysis. Hypothesis testing using these tools is a key element in advanced problem solving, so the loss of these tools has been a major challenge for practitioners of Six Sigma who use the Macintosh, but not anymore.
