How to find alpha and beta for inverse gamma distribution?

Question

I'd like to experiment with using inverse gamma distribution for my data set.

If my data was distributed normally, I would have to find sigma and median, and I would be all set.

For inverse gamma distribution, I understand that I'll have to find alpha and beta.

How do I do that?
