# Weighting

## Two Terms with Term Weights

In the **Weighting** dialog box, we have checked the box for **Weight Terms** and entered 50% for each term, (i.e. equal weights). The weights total 100, but it is not necessary for the weights to total 100. Term 1 will be 50/100 = 50% of the **Final Grade**. The same would apply if the weights were 40 for each term. Term 1 would be 40/80, which is still 50% of the **Final Grade**.

In the example the average is:

### Calculation

(T1 Average * T1 Weight) + (T2 Average * T2 Weight) / Total Weight = Final Average

(85.5 * 50) + (76.0 * 50) = 4275 + 3800 = 8075 / 100 = 80.75

More commonly, the final average is calculated by adding the term subtotals together and dividing by the number of terms if the terms have equal weights.

### Calculation

85.5 + 76.0 = 161.5 / 2 = 80.75

## Two Terms with Category Weights

The category weights have been added to the gradebook by checking **Weight Categories**. The weight row for assignments will remain empty when only term and/or category weights are used.

**Category by Term** subtotals are displayed to show that weights are applied within the term.

### Calculation

**Term 1**

Category Test:

Assignment 1 75

Assignment 4 92

Total 167/200 = .835 * 60 = .501

(Total points / Possible Points) * Category Weight

Category Daily

Assignment 2 90

Assignment 3 85

Total 175/200 = .875 * 40 = .350

Term 1 Average .501 + .350 = .851 * 100 = 85.1

Category Totals / Total Weight = Term Average

**Term 2**

Category Daily:

Assignment 5 65

Assignment 6 87

Total 152/200 = .76 * 40 = 30.4/40 = .76

Term 2 Average .76 * 100 = 76.0

Since only one category (Daily) was used in Term 2, 100% of the grade would come from that category (40/40 = 100%). Category weights for a term do not have to add up to 100.

**Final Average**

Term 1 85.1 * 50 = 4255

Term 2 76.0 * 50 = 3800

Total 8055 / 100 = 80.55

(T1 Average * T1 Weight) + (T2 Average * T2 Weight) / Total Weight = Final Average
