Compare two means

[Sebastian Mayer]

Hey all,

I have a very basic question for you:

I gave around a questionnaire (13 items) to 120 people, measuring a certain personality trait.
7 Items measure one facet of this trait, the other 6 items measure the other facet.

Now I have the overall mean for facet 1 and the overall mean for facet 2.

Which test can I use to find out, if those two means differ significantly or how the personality trait is distributed in the population?

Thank you for your answer.

S.

Within groups t-test. Same people complete both item sets. I think it reasonable to expect the scores to be correlated.

Or in the terms you'll find in the SPSS GUI, paired samples t-test.
