ANOVAis used for comparing means across three or more total groups. In contrast,ttests compare means between exactly two groups. Finally,contingency tablescompare counts of observations within groups rather than a calculated average. Sincettests compare means of continuous variable between groups, conti...

To compare means of more than two groups or multiple pairwise comparisons, we use a post-hoc test or ANOVA test. For example, we can use a t-test to determine if the recovery duration of common cold while consuming natural remedies is different from over-the-counter pharmaceutical remedies....
