You are obviously missing the point of split file!
Tell us about "Violation Manipulation "  Your warning suggests that it has one or more system missing values and together those missing cases have 0 variance or some other anomaly prohibiting calculation of the stats.
Perhaps post your syntax from the point of
SORT CASES BY blah blah blah.
SPLIT FILE BY blah blah blah.
T-TEST SOMETHING OTHER THAN blah blah blah.

Hi,

Yes I did a frequency and nothing is missing (it is one categorical variable, 1=male, 2=female, that I have split filed)

I’m not sure what you mean by a 2 or 3 way anova. It is one categorical variable with gender being split filed, and DV is perceptions of driving behavior pre and post manipulation. I would like to see if there are sig diffs pre and post DV for women and men separately (not together)
