For the factor analytic method, Little Jiffy, Mark IV, which was developed by Kaiser and Rice and reported in 1974 in EDUCATIONAL AND PSYCHOLOGICAL MEASUREMENT, a formula is derived for ascertaining factor scores. This formula is then employed to derive a second one giving an exact determination of the generalized Kuder-Richardson estimate of the reliability (or its square root, the domain validity) of scores on a Little Jiffy factor.
