You can weight final grades based on Assignment Groups. Selecting this option assigns a weight to each assignment group, not the assignments themselves. Within each assignment group, a percentage is calculated by dividing the total points a student has earned by the total points possible for all assignments in that group.

2) Click the Options icon.

3) Place a check mark in the box next to Weight final grade based on assignment groups.

4) Set the weights for each assignment group.

Note: Assignment Group weights can include two decimal places.

Note: The Total percentage can be greater or less than 100%.

Sample Weighted Grading Calculations

For example, if an assignment group included three assignments totaling 25 points, and a student's scores totaled 15 points, the student would earn 60% for the assignment group (15/25). This percentage is then multiplied by the selected group weight. Each assignment group calculation is added together to create the final grade.

For example, an instructor may create three assignment groups (A, B, and C) weighted at 20%, 50%, and 30%, respectively. The total score equation for a course with three assignment groups would be (percentage A x weight A) + (percentage B x weight B) + (percentage C x weight C) = final course percentage. If a student scores 75% in Group A, 98% in Group B, and 87% in Group C, the final score would be calculated as (.75 x .20) + (.98 x .50) + (.87 x .30) = .901, or 90.1%.

The final score calculation is changed if there are no graded items in an assignment group and the Treat Ungraded as 0 option is not selected. In this case, all assignment groups with graded items will be divided by their combined weight, and the assignment groups without graded items are removed from the equation. If the previous example were adjusted so Group C contained no graded discussions, assignments, or quizzes, the calculation for final score would be [(.75 x .20) + (.98 x .50)] ÷ .70 = .9143, or 91.43%.
