F = MSB/MSE,
The between-sample variance, S2B = SSB/k -1, where k is the number of samples or treatment and is often called the Mean Square Between, MSB = SSB/k-1,
The within-sample variance, S2W = SSW/n-k, where n is the total number of observations in all the samples is often called the Mean Square Within or Mean Square Error, MSE = SSE/n-k,
