Statistical Reanalysis of Canady's “The Effect of ‘Rapport’ on the I. Q.: A New Approach to the Problem of Racial Psychology”

Abstract

Because of the divergent interpretations of Canady's (1936) study, “The Effect of ‘Rapport’ on the I. Q.: a New Approach to the Problem of Racial Psychology,” a statistical reanalysis was performed. Results indicate that on the first administration of the 1916 Stanford-Binet, Ss obtained higher IQs with Es of their own race, while on the second administration, Ss obtained higher IQs with Es of the other race. For the total group, the Negro-white E order of administering the tests led to higher IQs than the white-Negro E order. Es' sequence of administering the test, however, did not significantly interact with Ss' race in determining inter-administration improvement. Results should be accepted with caution because of the methodological difficulties in the design of the experiment.
