If this overall ANOVA test is produces a significant result, you will learn how to test the hypotheses comparing any two groups using an ANOVA t-test formula. This formula is presented, explained, and a practical science example is used delineating the five steps needed to perform this test ...

Finally, lest we forget, ANOVA is a linear model, and we shouldcheck the residual plots for problems. That’s not possible in Excel! If you need to control for a covariate, you’ll need to perform anAnalysis of Covariance (ANCOVA)instead. Unfortunately, that’s not an option in Excel....
Similarly to Section 1.5 for ANOVA, we will show that MLR may not be a monotonic inclusion on the set {1,…,𝑘} of its predictors. More precisely, consider MLR F-test with k predictors and eliminate 𝑘−1 of them, all but i, obtaining k SLR problems, one for each predictor ...
