# Analog of the Chi Square Test for Variance for Non-normal Populations

If I recall correctly, if the population is normal, then if we take a sample of size n from it, we can use the Chi-Square test for variance to see if our sample's variance has a predetermined value or not.

Is there an equivalent test we can run if the population is NOT normal?

Surely that would just be the same test, but in reverse? If you have another specific distribution in mind, you could test for fit to that. – naught101 Nov 21 '12 at 6:47
What exactly do you mean by 'in reverse'? To clarify, I have a sample from a non-normal population (though I don't know what distirbution the population actually has). I want to know if there is a test I can run to check if the variance of my sample has a certain predetermined value or not. Chi-Square Test for Variance accomplishes this if the population is normal; however, I assume that when the assumption of normality doesn't hold, I can't use it. Or am I mistaken? – user17075 Nov 22 '12 at 2:21
