In Peergrade, each student receives an overall score in each course. This score is called the "Combined score" and is the combination of all submission scores and feedback scores across all assignments in the course.
On the Class settings page scroll down to the Combined score setting box. Here it is possible to set the weights for how submission scores and feedback scores are combined. The default setting is to allocate 50% weight to hand-ins and 50% weight to feedback:
In addition to setting weights on the submission score and the feedback score, a teacher can also set weights on the individual assignments (also on the class settings page):
By default all assignments count equal (each has a weight of 1.0).
When computing the combined score for a student, the procedure is as follows:
Compute the hand-in score on each assignment
Compute the feedback score on each assignment
Combine the hand-in scores by taking a weighted average over assignments (using the assignment weights) to get a total hand-in score
Combine the feedback scores by taking a weighted average over assignments (using the assignment weights) to get a total feedback score
Take a weighted average of the total hand-in score and the total feedback score (using the weights from combined score settings) to get a combined score
