The example is for a group of three students: Anne, Brenda and Colin. Each student is rated for their contribution by the other two and also assess her/his own contribution using the grading scale in Appendix 2.
| Group Members | Project processes | Individual rating | |||||
| 1 | 2 | 3 | 4 | 5 | |||
| A Anne | A | 3 | 3 | 4 | 3 | 3 | |
| B | 3 | 2 | 3 | 3 | 3 | (42) | |
| C | 2 | 2 | 3 | 3 | 2 | ||
| B Brenda | A | 4 | 4 | 3 | 4 | 5 | |
| B | 4 | 4 | 4 | 4 | 4 | (62) | |
| C | 4 | 4 | 4 | 5 | 5 | ||
| C Colin | A | 4 | 3 | 3 | 3 | 4 | |
| B | 3 | 3 | 3 | 3 | 3 | (49) | |
| C | 4 | 3 | 3 | 4 | 3 | ||
The individual weighting factor is then calculated from the formula:
| Individual weighting factor = individual rating/average rating |
| Average rating = (42 + 62 + 49)/3 = 51 |
| Anne's weighting = 42/51 = 0.82 |
| Brenda's weighting = 62/51 = 1.22 |
| Colin's weighting = 49/51 = 0.96 |
| Group project mark = 65 |
| Anne's mark = 65 x 0.82 = 53 |
| Brenda's mark = 65 x 1.22 = 79 |
| Colin's mark = 65 x 0.96 = 62 |
If the deviations from the group mark are thought to differ significantly from the spread of marks found in individual assignments, the individual weighting factor may be scaled up or down. For example, if in the above example the deviations were thought to be too large a scaling factor of 0.5 might be chosen. This would mean that the deviation of the individual weighting factor from the value of one (the weighting for a student with the average rating) would be halved. In the above example, Anne's weighting would then become 0.91 (mark = 59); Brenda's weighting would become 1.11 (mark = 72); and Colin's weighting would become 0.98 (mark = 64).
