q2 · i? · associational · r2

Concurrent-validity comparison in one school of 256 pupils: correlations by grade were 80, 69, 73, 40, 39, 84 (third through eighth), averaging 69. The author attributes the low sixth-grade coefficient to "the inaccurate marking of the teacher," whose pupils were marked almost all Good or Excellent.

"Coefficients of correlation were computed between the marks and the test scores for grades 3 to 8 in a school of 256 pupils."
