To calculate the weighted grade for each assignment type, lets look at this example:
The default weight values are:
- Lesson Weight – 25%
- Quiz Weight – 25%
- Project Weight – 25%
- Test Weight – 25%
Step 1: Look at the number of assignments and grades for each type for the unit
- 10 Lessons with grades of: 96, 87, 32, 83, 94, 77, 96, 88, 79, 63
- 3 Quizzes with grades of: 99, 100, 62
- 4 Projects with grades of: 72, 85, 97, 98
- 1 Test with a grade of: 93
Step 2: Calculate an average for each assignment type and multiply that average by the assignment type weight to get a Unit Grade by Type
To calculate an average, add all grades for each type and then divide by the number of assignments.
| Assignment Type | Grades | Total | # of Assignments | Average | Weight | Unit Grade by Type |
|---|---|---|---|---|---|---|
| Lesson | 98 + 87 + 32+ 83 + 94 + 77 + 96 + 88 + 79 + 63 | 797 | 10 | 79.7 | 25% | 19.925 |
| Project | 75 + 85 + 97 + 98 | 355 | 4 | 88.75 | 25% | 22.1875 |
| Quiz | 99 + 100 + 62 | 261 | 3 | 87 | 25% | 21.75 |
| Test | 93 | 93 | 1 | 93 | 25% | 23.25 |
| Weighted Grade for Unit | 87.1125 | |||||
Step 3: Add the Unit Grades for each assignment type to calculate the Weighted Grade for the Unit
The weighted grade for the unit is 87.1125 which is then rounded up to 87.11%
The example above assumes that the unit contains all four assignment types. If a unit does not contain an assignment type, for example, Projects, then the Projects weight is redistributed across the other assignment types so that the weighting always equals 100% for the unit.
