Dear Statlist experts,
I have a data set of the performance of graduate course participants (n=30). Each course participant first attempted a quiz (n=4 quizzes and five BCQs in each quiz) individually. Next, the same quiz was retaken as a group activity by randomly assigning participants to groups (4-5 participants). We hypothesize that the quiz scores of groups are higher than the individual quiz scores. One option is to use an interclass correlation between individual scores and group scores. But it is a cumbersome process to compare individual and group scores for 20 questions/4 quizzes. Is there a better way to analyse this data?
An example data set is attached for 9 students for the week three test/quiz.iq31-iq35 individuals scores in questions 1-5 of the quiz, gq31-gq35 group scores of same questions. iq3Tot and gq3Tot are the total scores in the individual quiz and group quiz respectively.
