**ANOVA (analysis of variance)** is a statistical method used to compare the means of three or more groups or populations, one of which is the dependent variable. It is used to determine whether the differences between the averages of the groups are statistically significant or stem from luck. ANOVA and Student’s t-tests probe into the same issue. The difference between them is that the t-test analyzes differences between two groups, while ANOVA does it between three groups or more.
