“…However, in most cases, the strength of relationship (r), evaluated using Cohen's conventions 68 (0.10 weak, 0.30 moderate, 0.5 strong), was a weak correlation between only part of the selection test or outcome measure (n = 9). 5,29,30,55,56,[59][60][61]67 In some cases, correlations were reported between a section of an admission test, 5,29,30,61,64,65 such as a single interview question, and/or small sections of the outcome measure, 28,30,31,54,55 such as a single examination result.
