MOE of a particular sort. MOE is most often applied to a single "mean" value. For xample, in this poll, the "mean" for Trump is 47.0%, and that single value has a margin of error.

The grey band accounts for MOE of two samples (two MOE's, if you will), and aims to describe the probability that the item with the higher sample average, actually has the higher value in the whole population.

the gray is the intersection of both MOEs.

i want Trump above the gray ;)
