This technique is intended to analyze variability in data in order to infer the inequality among population means. The application data were analyzed using computer program MATLAB that performs these calculations. http://pubs.sciepub.com/ajme/1/7/21/ajme-1-7-21.pdf one-way ANOVA testnormality testshomoscedasticity testsmultiple comparison testsMATLAB
