Looking for Statistically Significant Differences between questions


New Member
I would need to find a test to see if there are statistically significant differences between the responses to 100 questions which I administered to 30 participants. The responses range from 0 to 100. Of course I would like to rule out outliers (which I can deal with), but I need to compare the results for each question. What kind of test(s) can I run in SPSS?

More detail: I want to eliminate extreme scores so if some of the questions have scores closer to 100, I would like to identify those questions.

Thanks in advance!
