What is ANOVA

Analysis of Variance (ANOVA) is a statistical method used to analyze the differences between the means of two or more groups.

ANOVA is very similar to t-test, but it’s for more than 2 groups.

The steps are also similar to t-test.

Calculate overall mean. Note: $p_{mean}$ = 1
Calculate SS(means). Now we have multiple lines instead of two lines.
Fit the data and get the equation
$y = m e a n_{control} + m e a n_{mutant} + m e a n_{control2} + ...$
Calcualte SS(fit) for each lines
Calculate F-value
