However, convenience sampling can be useful in pilot or exploratory studies, or if limited resources do not allow selecting a representative sample [4]. Biomonitoring studies Webare called probability samples. Probability sampling has a certain amount of randomness built in so that bias or unbiasedness can be established and probability statements could be made about the accuracy of the methods (Scheaffer, Mendenhall, & Ott, 1996).
