This standard is based on the costs or time of the experiment and of administering the test. For example, if test administration costs are 7 % of the total experimental costs, the efficient value of the...

15 صفحه اولA basis for analyzing test-retest reliability.
Three sources of variation in experimental results for a test are distinguished: trials, persons, and items. Unreliability is defined only in terms of variation over trials. This definition leads to a more complet~ analysis than does the conventional one; Spearman’s contention is verified that the conventional approach--which was formulated by Yule--introduces unnecessary hypotheses.
