WebSlide 12 Comparing the Variance Estimates: The F Test n If the null hypothesis is true and the ANOVA assumptions are valid, the sampling distribution of MSTR/MSE is an F distribution with MSTR d.f. equal to k-1 and MSE d.f. equal to n T-k. n If the means of the k populations are not equal, the value of MSTR/MSE will be inflated because MSTR ... WebApr 14, 2024 · The hypotheses used in an ANOVA are as follows: The null hypothesis (H0): µ1 = µ2 = µ3 = … = µk (the means are equal for each group) The alternative hypothesis: (Ha): at least one of the means is different from the others WebThe F ratio is the ratio of two mean square values. If the null hypothesis is true, you expect F to have a value close to 1.0 most of the time. A large F ratio means that the variation among group means is more than you'd expect to see by chance. incyte jobs delaware
