ANOVA

ANOVA, or Analysis of Variance, is a statistical method used to compare three or more groups to see if there are significant differences in their means. Imagine you want to test different teaching methods on student performance. ANOVA helps determine if the differences in test scores among classes taught by different methods are due to the teaching methods themselves or just random chance. If ANOVA shows significant differences, further tests can reveal which specific groups differ from each other, helping inform decisions based on the results.
