Hmm, good question... I don't think so, sorry.Originally posted by gloria*
it is interesting what you say about the way marks are distributed-- do you know of anywhere I can look up to read more about it? Is it delved into online anywhere?
Though here are a few excerpts from some documents that I have hard copies of -
...
The performance of the 3 unit students as a group on the common 2 unit/3 unit examination determines their pattern of marks in the additional course. The marks of the 3 unit students on the additional course are adjusted so that as a group, these marks have the same mean, standard deviation and distribution shape as these students achieved on the common course.
...
The pattern of marks of the group of 3 unit students on the additional 3 unit paper is made to coincide with the performance of this 3 unit group on the 2 unit common paper. This is done by using a process called equipercentile mapping.
...
The marks of students in a 3 unit additional course are scaled according to the performance of these students on the common paper. That is, they are given the same mean, standard deviation and distribution shape they achieved on the common paper.

There's not really much more to it than that. Hope it helps.
