I'm not sure why you are being downvoted. I completely agree with you: it sucks to suck at maths because I believe this article brings very interesting information, information that could be very useful to me, that I simply cannot understand because I suck at maths.
Just skip over the meaty statistics in the middle of the article. The conclusion is that one method of analysis may show positive results even when another, more appropriate method would show negative results.
