| Abstract |
The importance of determining the appropriate sampling scheme (sample unit size (area x depth) and sieve mesh size) for quantitative macrobenthic studies is often underestimated. The paper presents a method for determining the optimum among a set of sampling schemes for detecting differences in location when the statistical model is a t-distribution for comparisons of two means. The authors define the 'optimum' scheme as the least costly scheme which is capable of reliably detecting a desired difference. Following a description of the method, the authors present an example showing how the method was used to determine the overall optimum sampling scheme among eight schemes to detect differences between a reference and a putative polluted site in the Everett Harbor area of Puget Sound, Washington, on 11 measures of community structure. |
