Detailed explanation-2: -What is Analysis of Variance (ANOVA)? Analysis of Variance (ANOVA) is a statistical formula used to compare variances across the means (or average) of different groups. A range of scenarios use it to determine if there is any difference between the means of different groups.
Detailed explanation-3: -The ANOVA method assesses the relative size of variance among group means (between group variance) compared to the average variance within groups (within group variance).
