The gradebook above shows a simple average calculation for one term with four assignments with 100 points possible for each. The Average is calculated by dividing the Total points received by the student, 258, by the Maximum points possible for the student, 300.
Total Points = 75 + 90 + 85 + 92 = 342
Maximum Points Possible = 100 + 100 + 100 + 100 = 400
342/400 = .855 * 100 = 85.50
Another term has been added to the gradebook and 2 more grades. The gradebook has been set to view the subtotal averages for term 1 and 2. However, no weights have been set in the gradebook so theAverage is still calculated by dividing the Total points the student received from all marking periods by theMaximum points possible from all terms for the student.
Total Points = 342 + 152 = 494
Maximum Points Possible = 400 + 200 = 600
494/600 = .8233 * 100 = 82.33
The average is not calculated by adding the term subtotals together and dividing by 2.
This calculation is often misunderstood when comparing manual calculations with GradeQuick calculations. You must use term weights if you intend to calculate the final average by averaging term averages.
