Linear Regression not work well with skewed marks
as this station

Constant Group Size method
Students are subjectively assessed as grades 1
to 4. The number of students attaining each
Grade is counted. The cut Pass/fail mark is set
so that the number of students passing and the
number failing is the same as that subjectively
determined by the assessor. Good for stations
with skewed marks

Number of students with each mark, within grades.
(Idealised)
Constant Group Size method
The problem is where to set the cut mark?
