SUMMARY Averaging of marks is well known to produce a reduction in spread, but such considerations are often ignored when using average marks to classify students in examinations. A simple analysis of variance mixed model can be used to correct for this behaviour, allowing for the different abilities exhibited by students. Examples are given of marks from a range of subjects at university degree level, and some a priori beliefs about these marks are substantiated.
