Mnemonic for platykurtic and leptokurtic

Question

I keep confusing terms leptokurtic and platykurtic. Is there a good mnemonic to help remember which is which?

"Lepto" means "little", "platy" means "flat", and both are equally unrelated to thickness of a tail. It also does not help that "lepto" (small) means excess positive kurtosis (had to look it up, btw. Again.)

Answer 1

You only need a mnemonic for one of them, right? For "platy-" think of a plain or plateau or platyhelminthes or platypus or platter. Or just think of the word flat--which sounds more like "flat" to you, platy or lepto?

Answer 2

I know this question is a few years old, but one I've come up with (not sure if original) is that a leptokurtic distribution has a big "peak" to lepto (leap over) and that a platykurtic distribution is a plateau and thus nothing or is something very small to jump over.

Yeah, it's dumb, but it works.
