Abstract

A rapid method is described for machine computation of biserial correlations in item analysis with several criteria. This method has been found to yield biserial correlations from punched IBM cards at the rate of about 41 per hour.

An alternative procedure would have been to code each item in a separate column and to use the reproducer to punch the criterion scores into multiple cards.
