In a one way anova the within- group variance
WebThe Mean Sum of Squares between the groups, denoted MSB, is calculated by dividing the Sum of Squares between the groups by the between group degrees of freedom. That is, MSB = SS (Between)/ (m−1). The Error Mean Sum of Squares, denoted MSE, is calculated by dividing the Sum of Squares within the groups by the error degrees of freedom. WebA One-Way Analysis of Variance is a way to test the equality of three or more means at one time by using variances. Assumptions The populations from which the samples were obtained must be normally or approximately normally distributed. The samples must be independent. The variances of the populations must be equal. Hypotheses
