8. You consider a study significant if it has a standard deviation of 0.07 because that's > 0?

Huh?

"TFA has a single study that they always trot out to show they have a positive impact at a standard deviation about 0.07,” said Vasquez Heilig. “While yes that number is bigger than 0, as researchers we do not consider that very significant...."

If your standard deviation is 0 that's already really, really ... uh ... weird.

This make sense to anybody?

(It's the kind of talk I expect from education researchers, not even sociologists.)
