Example 31
Step 2: Ten Separate Analyses
For each of the 10 completed datasets from Example 30, we need to perform a
regression analysis in which sentence is used to predict wordmean. We start by
opening the first completed dataset, Grant_Imp1.sav, in SPSS Statistics.
E From the SPSS Statistics menus, choose Analyze > Regression > Linear and perform the
regression analysis. (We assume you do not need detailed instructions for this step.)
The results are as follows:
We are going to focus on the regression weight estimate (1.106) and its estimated
standard error (0.160). Repeating the analysis that was just performed for each of the
other nine completed datasets gives nine more estimates for the regression weight and
for its standard error. All 10 estimates and standard errors are shown in the following
table:
