Abstract
The purpose of this Short Communication is three-fold: to make the case that the question of grid sufficiency in LES should be viewed as a hypothesis test, to demonstrate how this can be done using standard tools from statistics, and to illustrate how this leads to transparent ways to both judge grid sufficiency and to make decisions about how much averaging time is required to make that judgment.
