The Simple weighted mean of grades aggregation method is best for people who use a combination of points and percentages. This aggregation type does not allow you to set a weight for items or the categories; it simply uses the inherent weighting you've established by setting different maximum point values. For example, a 75-point item is worth more than a 25-point item. If you want all the student scores added together and divided by the points possible to obtain a percentage, use this aggregation. This aggregation also easily allows teachers to flag items as extra credit, if that option is needed.


Simple Weighted Mean sums the scores the student has earned and divides by points possible to arrive at a percentage.
6/10 + 8/10 + 88/100= 102/120 (85%)

Empty Grades simply indicates that a grade has not been entered in the gradebook. It may be empty because a student has not made a submission or that the teacher has not yet graded the item. Empty grades display as dashes in the Grader Report; they are different than scores of zero. Zeros are calculated, but dashes (empty grades) count towards the overall grade depending on what the teacher in the site has selected.

By clicking Exclude Empty Grades, the teacher is displaying a total that only reflects the graded items in the course, and the overall grade does not include ungraded items.
