An ANOVA experiment involves 4 groups and has 24 experimental units or data points. If I want to test my hypothesis at a significance level of 0.01, what should be the critical value to use for my test?

4.43

4.94

2.38

3.10

Say I perform two experiments to test the difference between the means of a variable in 4 different populations (or groups). In the first experiment, I find that between group MS = 1000 and within group MS = 200 and in the second experiment I find that between group MS = 2000 and within group MS = 800. In which of the two experiments are the four population means more likely to be different?

The First experiment

The Second experiment

It depends on the significance level
