ANOVA (Analysis of Variance)
A statistical technique to test the degree to which two or more groups of data vary or differ in a research. Large variance usually indicates that there was a significant finding from the experiment.
Test and determine whether the difference between the data groups exists, over simple incidental likelihood.

BrandIdea’s Implementation:
To test the population which is normally distributed, test and deal with outliers, test for homogeneity of variances.
