Analysis of Variance
Document Actions
Analysis of Variance is a statistical test for assessing whether the means of more than two groups are equal. ANOVA is an extension of the 2-independent samples t-test, allowing for comparison of more than two groups.
Example: If, in a program evaluation, you want to compare an outcome (e.g., posttest knowledge of ecology) for three groups (e.g., students who did not visit your center, students who visited for one day, and students who visited for one week), you could use ANOVA to test whether mean knowledge of ecology scores for the three groups are the same or different.
