I have two groups (1) (n=30 and (2) n=40). I asked 28 survey questions and have the mean average for each question from each of the two groups.

When I try to analyze by comparing means, independent t-test or any other, I don't see any values for sig. Am I setting up my data incorrectly?

Column 1 (treatment) I have 1 and 2 vertically

Column 2 through 29 Q1, Q2, ... with the mean averages listed for each group vertically.

Mean averages were calculated and I used a 5-point Likert scale in the survey.

What am I doing wrong?

Thanks in advance for any help
