I'm not a math wizard and now I need to calculate the mean and s.d. of the product of two variables. Apparently there is a delta method that should be able to do the trick, but I don't know how to apply it. I have SPSS, should that be able to help me out?(adsbygoogle = window.adsbygoogle || []).push({});
