Grades is a way to estimate how well a student has understood a subject.
But what influences these grades? Is it only the students motivation and
determination to study? His talent? Or does the examiner have a big
influence on the grade? We have evaluated this last question by using
statistical modelling, multiple linear regression and ordered probit
regression. Our findings shows that the grade a student received on the
exam is correlated with the examiner. However we did not see a systematic
difference of an examiner’s performance over a period of time for a given
course. For the reader that is unfamiliar with statistical modelling, a brief
introduction to this field is provided.
