Gradebook Aggregations • Mean of Grades • Sum of Grades • Weighted Mean of Grades
Mean of Grades 96 + 76 + 70 + 100/4 Calculates the average of grades. The sum of all grades divided by the number of grade items. 85.50 89.25 +89.89 267.64 267.64/3= 88.21
Sum of Grades 24 + 38 + 7 +3 = 72 72/88 = 81.82% The sum of all grade values. Earned/possible 1008/1048 = 96.18%
Weighted Mean of Grades • Items, or categories count toward a certain percentage of the overall grade. • 20% - Course Tasks • 50% - Projects • 30% - Assessments
