VIDEO: It's easy to run a regression in Excel and you only need to understand a few data points to make sense of the results.

Next, have Excel run the regression on the two columns of return data you generated. Under the Data menu, the Data Analysis button allows you to select Regression.

To use the package, run Excel, and File / Open / KStat.xls. If you've got your Excel "paranoia" settings turned on, you might be prompted with a few warning windows. DO permit macros to run.
