Correlation number of scores occurring per year on test × test hardness

rn/yr × q = -0.12 (over 79 tests with at least 16 scores each)

Although this appears a slight negative correlation, one expects a somewhat larger negative correlation with the true, population-independent, test hardness. This correlation means that easier tests are more popular than harder tests. The fact that hardness as meant here is computed in relation to the group of candidates having taken the test may attenuate the correlation toward zero, on the understanding that a (truly) harder test will attract a smaller sample with a higher average level, and that therefore the average score of the sample shifts upward with true hardness, thus hiding the correlation.

Conclusions summarized

  1. Homogeneous (one-sided) tests are more popular than heterogeneous (multi-sided, mixed-item) tests;
  2. Easier tests are more popular than harder tests;
  3. Heterogeneous tests are not harder on the whole than homogeneous tests;
  4. Of the homogeneous tests, verbal tests are the most popular, even though in a foreign language for many of the candidates;
  5. Of the homogeneous non-verbal tests, visual-spatial tests are the most popular;
  6. The various types of homogeneous tests do not differ much in hardness, although numerical and spatial tests are somewhat easier than logical and verbal tests.
