When I open the dialog box for "ttest" (Two-sample mean-comparison test),
the options for unequal variances and Welch's approximation strangely
overlap, whereas in the Two-group mean-comparison test, I find them below
the confidence level switch and a centimeter apart. The recent 22/1/08
update does not seem to have fixed this. Any ideas?
