Little Jiffy Factor Scores and Domain Validities
暂无分享,去创建一个
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.
