The group-project mark combines two scores using a geometric mean:
where \(M \in [0, 100]\) is your individual measurable contribution score (engagement: being present and contributing to the meeting, as evidenced by the minutes) and \(E \in [0, 100]\) is the shared effective contribution score (the group's mark). The full definitions are on the Assessment page; the three scenarios below show how the formula behaves for three typical kinds of group.
A group of four produces a strong project (\(E = 74\)). Student D was recorded as engaged in one of five meetings (\(M = 20\)).
| Student | \(M\) | Final mark |
|---|---|---|
| A | 100 | 86.02% |
| B | 80 | 76.94% |
| C | 80 | 76.94% |
| D | 20 | 38.47% |
Student D cannot pass on the strength of their group's work alone.
Student A was recorded as engaged at all five meetings (\(M = 100\)). The group's output is weak (\(E = 42\)).
| Student | \(M\) | Final mark |
|---|---|---|
| A | 100 | 64.81% |
| B | 60 | 50.20% |
| C | 60 | 50.20% |
| D | 40 | 40.99% |
All four students attend consistently. The project is solid (\(E = 68\)).
| Student | \(M\) | Final mark |
|---|---|---|
| A | 100 | 82.46% |
| B | 80 | 73.76% |
| C | 80 | 73.76% |
| D | 60 | 63.85% |
