Hello All, I have been intrigued by the comparisons of team scores on the gRATs to the High, Low and Mean scores on the iRATs. Lately I've had the opportunity to keep track of scores following different team learning experiences. It struck me as a little odd that some teams actually score lower than the highest member on that team. I've attributed this to 1.) inexperience working as a team, 2.) withholding by the brighter team member (for whatever reason), and 3.) lucky guessing by unprepared students that cannot help their team experience the same success. Perhaps someone could posit another cause? Low High Mean Team Score Gain above high Gain above mean Gain above low Team1 56% 67% 61% 72% 6% 11% 17% Team 2 50% 89% 78% 94% 6% 17% 44% Team 3 67% 89% 78% 94% 6% 17% 28% Team 4 61% 83% 78% 89% 6% 11% 28% Team 5 50% 89% 67% 78% -11% 11% 28% Team 6 56% 89% 72% 83% -6% 11% 28% Team 7 72% 89% 78% 94% 6% 17% 22% Team 8 67% 78% 75% 89% 11% 14% 22% Team 9 72% 89% 78% 89% 0% 11% 17% Team 10 56% 78% 67% 83% 6% 17% 28% My real question, however, revolves around the analysis of this data once it is collected. Has anyone used a reasonable statistical test to compare individual scores on the iRAT to the team scores on the gRAT? I have been considering ways to compare performance of several teams on gRATs (dependent variable) following the use of an educational intervention (independent variable). All of the students will have taken the iRAT prior to the intervention so I could compare team scores to high, low and mean individual scores for each group also. Exp. (iRAT->X1->gRAT) vs. control (iRAT->gRAT->X2).
