| Abstract: | Corrections made by the present author (see record 1970-05886-001) for suggested spuriousness in Q. McNemar's (see record 1951-05872-001) formula for determining the validity of a short form of the Wechsler-Bellevue Intelligence Scale were rejected by McNemar (see record 1974-24264-001) as being based on fallacious reasoning. The present author replies that correlated errors responsible for the spurious correlation given by McNemar's formula affect only the covariance, not the variances, of the full scale and the short form.
