Abstract

Letter series and number series tests, comprising items based on identical rules, were administered in a counterbalanced design to 320 undergraduates in order to determine the similarity of factorial structure by means of Tucker’s coefficients of congruence. Results indicated that the letter and number series tests, in which each item in one had a same-rule counter-part in the other, possessed limited factorial similarity because only 4 of the 8 identically constituted factors yielded coefficients of congruence between .80 and .91 (median = .85). Examination of item-wise patterns of responses of the persons, whose total scores on the letter series tests were five or more points lower than their total scores on the corresponding number series tests, revealed certain tactics of this group (n = 92) that might account for the lack of adequate factorial similarity.
