2 X 2 Analysis of Variance

This program computes the F tests for a 2 X 2 factorial design, tests of the main effect of independent variable A, the main effect of independent variable B, and the interaction between A and B. Different subjects are observed in each of the four groups and there is no matching.

• Enter the mean, standard deviation (n-1), and n, the number of subjects, for each of the four groups.
• Key "Enter" after each value.
• Click the "calculate" button to compute statistics.
• To change a value, double click on the number then enter the new value.

To print the results, cut and paste to your word processor.
