But suppose you combine five samples at a time into 10 pooled samples. In the first round of testing, you use 10 tests on the pooled samples. Suppose four of the tests are positive. In the second round of testing, you test the 4*5 = 20 samples that were in the four pooled samples.
WebThe assumptions on the means are the same as that of the ANOVA; that is, they are assumed to be from normally distributed populations with common variance . The grand mean is , and the pooled estimate of the common but unknown variance is. Note that the pooled estimate of the variance is identical to MSW in the ANOVA.
