Moodle converts all grades to a percentage value and then aggregates the grade according to the strategy that you select. There are over 8 different aggregation methods.
Method | Definition |
---|---|
Mean of Grades | The sum of all grades is calculated and then the total is divided by the number of graded items. |
Weighted Mean of Grades | The sum of all grades is calculated, the specified weight is applied to the grade, and then the total is divided by the sum of all weights. |
Simple Weighted Mean of Grades | The sum of all grades is calculated ,the Maximum Grade Value for the assignment is applied as the weight, and then the total is divided by the sum of all weights. |
Median of Grades |
Grades are arranged in ascending order, and then the median value is chosen. If there are even grades, the two middle values will be chosen and then divided by 2. |
Natural | This will be the sum of all grade values, scaled by their relative weight. The maximum grade of the category is the sum of all the maximum grades of the aggregated items. |
Note. You can choose an aggregation method for each Grade Category.
Click Edit > Edit Settings on a Course Category.
In Edit Settings under the Aggregation drop-down, choose the appropriate weight.
Note. If you select Weighted Mean of Grades you will be able to input the weight of each item within the category on the Gradebook Setup page.
