Analysis of Variance (ANOVA) evaluates mean differences between two or more treatments or populations (Gravetter and Wallnau, 2013). Functionally, it performs the same kind of analysis as a t-test, but the advantage of an ANOVA is that an ANOVA can compare more than two groups at once, whereas a t-test is limited to two groups.
Below are variations on the ANOVA with different groups.
Below are various calculators that supply descriptive statistics for sets of data. It is compatible with sample sizes between n=6 and n=12.
