How/where to mention research skills in SoP

[Cesare]

Right now I mention my statistical training in my intro, but it is a little awkward I think. I am applying to programs that are quant heavy, so I want to emphasize it. I don't want to leave it for the very last paragraph. The body paragraphs are all about research and the questions that I am interested in. I don't want to go into detail there about my training because I don't want the adcom to think I am motivated by methods rather than substantive interests. I just don't know where to discuss my training....

I discussed my training/experience with useful research skills when I discussed my previous research. For example something like "I worked with Prof X on Study A. I analysed the data using Method B and we ended up with result C." Or something like that.
