iRATs were conducted out of class via the Internet (we use the Moodle
platform, with time limit of 1hr). We use IF-ATs for tRATs. Average iRAT
in this team was 12.8 and average tRAT was 15.8. The iRAT scores (scale
0-20) within this team (average of the best 4 of 5 iRATs) were 12.5, 13,
13.5, 12, 13.5, and 12.5. iRAT count 25% of the final "TBL score" for
each student. The final grade for a student is 40% exam + 60% TBL. tRAT
are counted together with applications for the final team score.

I've not asked.

108, 94, 98, 122, 68, 110

The individual team score is the team score x peer evaluation / 100.
> 5) Did members' final exam scores affect other team members?
No.
