a difference in differences. He has a normally distributed interval
outcome variable and a categorical predictor measured at two time
points.
The simplest way to do this is probably:
-regress outcome i.predictor##i.time-
The coefficient of the interaction term in the output will be the mean
difference in differences, and the standard error he seeks will appear
right next to it.
Hope this helps.
