Hi

I have given questionnaires to 50 participants, and i want to see if there are any differences in the mean values between those participants with an even compared to an odd questionnaire number. So i have split the participants into 2 groups- group A(even nos) and group B(odd nos). I have the means for group A and group B.

I was wondering if there is a correlation caclulation i can do on these two means, to see how different the means are from each other?

Many thanks
