# Determine Chi Square Group Differences in multiple choice questionnaire

I'm trying to determine if there is a group difference in answering a multiple choice question.

For example, I want to answer the question of, do "Change Instigators" (group A) answer "communication" as a strength more often than the group mean (average of group A, B, and C). You can select up to 2 answers, "communication" being one of 5.

Here's how my data is formulated:

Strength              Change Instigators     GroupB     GroupC
