Testing Variances in Psychological and Educational Research.
Ramsey, Philip H.
Journal of Educational Statistics, v19 n1 p23-42 Spr 1994
A review of the literature indicates that the two best procedures for testing variances are one that was proposed by O'Brien (1981) and another that was proposed by Brown and Forsythe (1974). An examination of these procedures for a variety of populations confirms their robustness and indicates how optimal power can usually be obtained. (SLD)
