However, the current study contains a relatively small sample size (N = 18; participants at Level 2) in relation to a large sample of repeated measurements nested within persons (the medians of frequencies of 10-s measurement intervals range from 101 to 184 measures per person; Level 1).
However, most of these exposure studies have relied on single spot urine samples instead of repeated 24-hr urine collections.

But to help us, we know that if the sample size is large enough, the MEANS of repeated samples will be normally distributed with a mean of μ and a standard deviation of σ/√n (standard error).
A limitation of repeated samples is that each sample may differ in important ways that are unmeasured.
Somehow his productions build momentum even when they revolve around a handful of repeated samples.
For nitrotyrosine blots the ratio was based on total nitration of repeated samples.
An additional internal cross-validation test of the classifier validity was done by analysis of repeated samples.
The differences that occur are due to the reduced weight of repeated samples in the analytical model (Table 2).
The strategy consisted of repeated sampling of a section almost perpendicular to the Balearic Current situated to the north of Mallorca Island.
