How do I change my gradebook aggregation to ‘Weighted Mean of Grades’?

By default, the Moodle gradebook aggregation (the way it adds your grade values) is ‘Simple Weighted Mean of Grades.’ This is points-based, and does not allow you to weight categories or items.

If your syllabus is set up with various categories (e.g., Quizzes, Homework, Papers, etc.) or grade items (e.g., Mid-term Exam, Final Presentation, etc.) carrying different weights (e.g, Quizzes – 20%,  Papers 40%, Final Presentation 20%), then you want your gradebook aggregation to be ‘Weighted Mean of Grades.’

EXAMPLE of a “Weighted Mean of Grades”

Assignments – 35% of course total

Quizzes – 15% of course total

Final Exam – 45% of course total

Participation – 5% of course total

COURSE TOTAL = Weighted Average
