Why does the CHE not caluclate a league table?The CHE UniversityRanking gives ranking groups rather than individual numeric ranking positions in a league table. HEIs are allocated to a top group, middle group and bottom group. This is done since the assigning individual ranking positions has the danger to misinterpretate, minor differences in the numerical values of indicators as real differences in quality/performance. League tables suggest that each difference in ranking position marks a real difference and hence they tend to exaggerate the differences between institutions. By contrast, the group ranking method assures that the top and bottom groups can be statistically distinguished clearly from the total average value. However, differences within the groups can be considered insignificant, and for this reason the HEIs within one group are listed in alphabetical order.
