> While reviewing a document, I came across a table that lists "
> Appropriate Number of Soil Samples to Collect" as a function of the land
> area. The table also includes a column with an estimated coefficient of
> variation (CV). For example, for a 7 acre (28000 square meters), it says
> to collect 7 samples, which would result in an estimated CV of 15%. I've
> been told that the values in the table come from an EPA document. To my
> dismay, I've not been able to verify this. I understand that statistical
> methods exist to determine the number of samples required. I'd like to
> see how the table was derived because to use the table I'd like to feel
> comfortable in understanding where it came from.

> If anyone has a clue, I'd appreciate it.
