This article provides a study note on analysis of variance. It is a measure of variation among treatments/genotypes/replications, etc., and is obtained by dividing the sum of squares (SS) by corresponding degrees of freedom (n — 1) to get mean sum of squares (MSS), i.e., variance. Variance parameter widely used in statistical analysis is the comparison among different sample means. [...]
