 Description  « Hide
I will highlight the cell in the main question table for question positions that have a negative covariance of position grade with overall total grade for attempts and highlight the cell in the individual question data table. We will include the message :

"Negative covariance of grade with total attempt grade"

We will also include a help button after this message to click on that will explain what this means.
