ANOVA
Two-way ANOVA *****
Let you choose sample size, group means and mean square error, and see how these factors affect the sum of squares decomposition both numerically and graphically

Unequal n ANOVA and Types of Sums of Squares  ****
Let you input data and see how ANOVA analysis changes as more data points are added.

Robustness of t test and ANOVA  ****
Three-type analysis(ANOVA I,II,III) in two way factor analysis are shown. See how Type I error rate and power of t-test
(two group ANOVA) change  when the errors are not normal, or when the error variances are not the same in different groups.

One-way ANOVA  ****
Demonstrate the partioning of sums of squares in one way ANOVA. You can add more data points to see how the analysis is affected.
