Detailed explanation-1: -The second is one-way analysis of variance (ANOVA), which uses the F-distribution to test to see if three or more samples come from populations with the same mean.
Detailed explanation-2: -F-statistic, also known as F-value is used in ANOVA and regression analysis to identify the means between two populations are significantly different or not. In other words, F-statistic is the ratio of two variances (Variance is nothing but a measure of dispersion, it tells how far the data is dispersed from the mean).
Detailed explanation-3: -In ANOVA or analysis of variance, f-tests are frequently used in a statistical capacity to determine the equality of different means when there are three or more groups involved by evaluating the variations both between and within the different groups.
