Is ANOVA a multiple comparisons test?

The Analysis of Variance (ANOVA) test has long been an important tool for researchers conducting studies on multiple experimental groups and one or more control groups. A class of post hoc tests that provide this type of detailed information for ANOVA results are called “multiple comparison analysis” tests.

What are the hypotheses for the ANOVA test?

To compare the results of the excel ANOVA test, we can frame two hypotheses, i.e., “Null Hypothesis” and “Alternative Hypothesis.” The Null Hypothesis is “there is no difference between scores of three students.” The alternative Hypothesis is “there is at least one of the mean is different.”
