moderation question (1 Viewer)

just wondering, let's say in a cohort's internals we have the following ranks and scores
Student A Rank 1: 76%
Student B Rank 2:70%
Student C Rank 3:68%

External scores (random students achieved):
Highest mark: 95%
Second highest: 80%
Third: 75%

How would this be moderated... what would each of those students get for their 'new' internal mark? (since there's big differences between the scores attained externally)

For the particular example you have given, I suspect that the moderated marks given for ranks (1, 2, 3) will be (95, 80, 75).

The reason for this is because internally the gap between rank 1st and 2nd (6%) is 3x the gap between rank 2nd and 3rd (2%). This 3x relativity in the gap also happens to be reflected in the external marks (15% vs 5%) so no further adjustment is required.

This is a perfect example of demonstrating that moderation only cares about the relative gaps between students, not the absolute gaps.
