Difference in Standard Deviations

Enter the observed PERFORMANCEs in each context below, separated by commas and/or spaces. The test statistic will be computed as:
(SD in context 1 - SD in context 2).

Context 1:
Context 2:
Calculate the observed standard deviation in each context and the difference between them.

Simulate differences in standard deviations and get those differences, arranged from smallest to largest.
The applet will keep track of all of your results until you hit "Reset."
