regressions have an explanatory power between 6% (The company in an international
setting) and 39% (Business Statistics), which, as mentioned in the introduction, was
expected. 19 What these numbers indicate is that the admission characteristics used can
explain at most 39% of the variation in the grade in individual B.Sc.IB courses – the
rest of the variation is explained by other factors that affect performance and learning
in general.
Focusing on which variables turn out to be significant, it is seen that whether a
student has been admitted through quota-1 or quota-2 affects the grade quite a lot in
courses like Microeconomics, International Business Environment, Macroeconomics,
International Economics, MIS, Corporate Finance and Business Statistics. Moreover,
19. In general, however, small R-square values are not unusual with this type of micro-data.
