WebMSB/MSW is an F distribution with MSB d.f. equal to k- 1 and MSW d.f. equal to n T - k. If the means of the k populations are not equal, the value of MSB/MSW will be inflated because MSB overestimates σ 2. Hence, we will reject H 0 if the resulting value of MSB/MSW appears to be too large to have been selected at random from the appropriate F WebStep 7: Determine the MSB and the MSE.
