ANOVA Test: Analysis of Variance Definition, Types and Examples

A one-way ANOVA (“analysis of variance”) compares the means of three or more independent groups to determine if there is a statistically significant difference between the

This open textbook covers common statistics used in agriculture research, including experimental design in plant breeding and genetics, as well as the analysis of variance, regression, and An Analysis of Variance (ANOVA) is a partitioning of the total sum of squares. In the second line of the expression below, we are adding and subtracting the sample mean for the i th group. Analysis of Variance (ANOVA) is a statistical method used to test differences between two or more means. It may seem odd that the technique is called „Analysis of
