Abstract:

A well known test for equality of normal population variances, based on sample variances, was introduced by Cochran 1941. He introduced a test strategic which compares the largest sample variance with the sum of the sample variances. Clearly the intent is to discover if one variance is an outlier too large, and, in general, H sub o will be rejected for large values of Z. Tables of various percentiles are given for various values of n and k.
