The daily assignments in this gradebook have a variable number of points. Our previous explanations used only assignments with 100 possible points. The assignments are weighted based upon the possible points. If an assignment has more points possible (100) then it has more weight than an assignment that has less possible points (20).
The final average is calculated by dividing the total number of points the student received (Tot) by the maximum points possible for that student (Max):
229/265 = .8641 * 100 = 86.41
To calculate the term average, you must first determine the Category average. The category average is calculated by dividing the sum of the test scores by the sum of the possible points.
The category averages in term 1 would be calculated as:
Test (75 + 92)/(100 + 100) = 167/200 = 83.5)
Daily (20 + 9)/(20 + 10) = 29/30 = 96.6
The category weight is applied to each category average:
Test 83.5 * 60 = 5010
Daily 96.6 * 40 = 3864
The term average is calculated by summing the weighted category averages and dividing by the sum of the weights:
(5010 + 3864) = 8874/(60 +40) = 88.74
Weighting is determined from both Possible Points and the Category Weighting.
