Material Detail

This applet displays boxplots of independent random samples drawn from 4 populations and an ANOVA table for the comparison of the population means. The user can adjust sliders to change the means and standard deviations of the populations. As this happens, new samples are chosen and the boxplots and ANOVA table are updated.   The applet includes a pie graph that shows the proportions of within and between group variation and a graph of the F distribution displaying the area corresponding to the p-value. These are also updated as the samples change.
