this is a very poor and convoluted explanation of a main effect

Definitely, note there is no link of discussion of the term "effect" in this definition. In fact, the term "main effect" is frequently used incorrectly. —Preceding unsigned comment added by 208.180.238.126 (talk) 21:06, 13 May 2010 (UTC)

Incomprehensible to lay encyclopedia readers
I was reading a presentation about clinical trials that used the term "main effect" and came here to try to understand what it means. Result: I still don't understand what it means! I am not a statistician, and this seems to have been written for other statisticians rather than for an encyclopedia. Are we absolutely sure there isn't a short sentence that captures the rough meaning without erring or requiring specialized knowledge (like "dependent variable")? Or a lede paragraph that isn't full of weasel words and terminology? Or a short example like "When I tried to lose weight, the main effect was to make me hungrier."? We can do better!
