Help with choosing a statistical test!

[rheighton]

I've randomly been assigned a data set to statistically analyze, but cannot figure out for the life of me. Here's what I have:

-Excel file to be imported into Statistica
-1264 rows of data
-15 columns
-first column: student id numbers
-columns 2-15: binary data for questions 1-14 on a test (1 = correct, 0 = incorrect)

I'm not even sure what I should be making of this data set, as far as I know, the only test that I can run on binary data is a logistic regression, but I would have to run a separate one for each question column, which would mean 14 separate logistic regression equations.

If anyone could give me any guidance as to how I should approach this analysis I would GREATLY appreciate it!

Thanks!

Question Effectiveness is always interesting. Questions everyone gets right do not differentiate very well. So also questions no one gets right.

It might be interesting if you know what students were in each exam session - assuming there were multiples.
