Agricultiral Soc. Cambridge, 1972:157163), resulting in ( for the anomalous condition and = œ #"Þ& 7 œ %)Ñ " = œ "*Þ%& Ð8 œ %&Ñ # for the non anomalous condition. Test for the equality of variances versus either one of the populations have the larger variance (using two seperate onesided test) at a significance level of by using the value !Þ"! : approach....
