In one of the questions, there 5 columns (Monday - Friday) and 4 rows (excellent, good, fair poor)
Normally, dof is 4*3= 12
We're asked to combine Monday-tuesday and wed-thurs-fri and also combine excellent-good and fair-poor
So our columns are now 1. Mon+Tues 2. Wed-Fri
Our rows are now 1. Excellent+Good 2. Fair+Poor
Now, what will be the dof?
This Q was in Nov 2008 paper, IAI
