StatPak - Excel plug-in
Once data is entered into an Excel spreadsheet, double-click on StatPak, while your spreadsheet is open on the desktop. An extra drop-down menu will appear on your menu bar.

Highlight the data (including the label) and choose the appropriate statistical tool you'd like to use:
• Five Number Summary
• Histogram
• Box Plot
• Normal Scores Plot
• Chi-Squared Test

The information or graph will appear on a new worksheet. Copy and paste it on the originating worksheet that has the data.

StatPak doesn't seem to work in the latest version of Excel (PC Office 2007, Mac Office 2008).
