A friend who tends to do very interesting (and often confidential) research about media just sent me this lovely diagram. Of what, you ask? Your guess is as good as mine.

Said friend writes: “That’s a charmingly normal distribution… I love it when, every now and then, data turns out exactly like you want it to… I actually know what’s going on in the data, and what X and Y represent… I just can’t talk about it.”

I’m intrigued.
