Regression
Using
the Regression Function
The
Regression function in EZAnalyze allows you to conduct
a statistical hypothesis test of the ability of a single
predictor (or set of predictors) to predict scores on a dependent
variable (criterion). Since this is an Advanced feature
of EZAnalyze, it will not
be
discussed
at length here. Feel free to consult a statistics textbook
or the Internet for information on what Regression is and
how it works. If you are already familiar with Regression
and want
EZAnalyze to crunch the numbers for you, read on!
NOTE: This is the only procedure in EZAnalyze
which relies on the 'Analysis Toolpak - VBA', provided by Microsoft.
Not all Excel installations contain this program. If your installation
does not have the Toolpak, you will not see the Regression
option on the EZAnalyze Advanced menu.
To
perform a Regression on your data, select "Advanced" from the EZAnalyze menu in Excel, and then choose "Regression".
When
the "Regression" dialog box appears, select a
criterion (dependent) variable from the list on the left,
and your predictor(s) from the list on the right. When
you are satisfied with your choices, click OK.
When
you click OK, a results report will
be printed on a separate sheet for your review. (click
on "results report" for information on how to
interpret this analysis)
