This template performs the standard F-test for equality of population variances. Given a sample s1 of size n from population p1 and another sample s2 of size m from population p2, the ratio (svar1/svar2)/(popvar1/popvar2) has an F distribution.

This template computes the sample standard deviations and then compares their ratio to an appropriate F distribution (specifically one with n-1 and m-1 degrees of freedom, respectively). It then reports the p-value of obtaining a result as extreme or more extreme than the result obtained given that the chosen null hypothesis is true.
