Desk four lists least frequencies to get applied at Every website determined by by far the most frequent sampling advised while in the referenced advice doc.
The entire higher than applies only to normally distributed measurement variables. For measurement knowledge from the extremely non-standard distribution, bootstrap methods, which I will never talk about listed here, might produce superior estimates of The boldness limits.
