Explanation:
Detailed explanation-1: -Analysis of variance (ANOVA) is the statistical procedure of comparing the means of a variable across several groups of individuals. For example, ANOVA may be used to compare the average SAT critical reading scores of several schools.
Detailed explanation-2: -For a comparison of more than two group means the one-way analysis of variance (ANOVA) is the appropriate method instead of the t test.
