Cascio (1989, 1991) presented a method of converting a measure of change in performance due to a training intervention expressed in standard deviation units to a measure expressed in percentage change in performance. Cascio asserted a direct relationship between the two, based on properties of the normal curve; however, an additional parameter-the ratio of the standard deviation of performance to mean performance-is also needed to make this conversion.
