ANOVA (Analysis of Variance) Statistical Tests

Bartlett’s Test of Homogeneity of Variance

Used to test if the sample variances of multiple samples are different. In ANOVA test below one of the assumptions of each test is that the variances of each sample are equal.

Singe Factor Analysis of Variance (ANOVA)

Single Factor ANOVA tests whether the means of two or more samples are different through the use of the analysis of variance (ANOVA).

Two Factor Analysis of Variance (ANOVA)

Tests whether the means of two or more samples are different through the use of the analysis of variance (ANOVA). Also tests whether the means of two or more treatments are different. The data is organized in a two-way classification of treatments (rows) and samples (columns).

Tukey Kramer Test

Post Hoc test used to determine which sample pairs are significantly different from each other. It is commonly used after a Single Factor Analysis of Variance (ANOVA) to determine which sample pairs are responsible for a significant result.
