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?

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).
'Looking forward to hearing your ideas and experiences,
