ANOVA (Analysis of Variation) is one of the widely used statistical tool to determine if variable X has impact on output. Variable X is discrete variable while Regression can be used in case X is a continuous variable.
In this case, we compare the mean values to see if the variation between the mean is significant and is tested by using F-Statistic. We calculate mean squared difference between the variables and mean squared difference between the output for a given variable.
Null Hypothesis
H0 : U1 = U2 = U3
H1 : Means are NOT Equal
