Sample size
Description
Sample size is an ambiguous term. (1) Size can be measured as an extensive quantity in terms of mass mS [kg], volume VS [m3], or energy ES [J] of a pure sample S. If the sample consists of countable entities X, the count NX [x] in sample S is an elementary quantity, in contrast to the extensive quantities used as indicators of sample size. (2) In statistics, however, the term 'sample size' does not refer to the individual sample, but indicates on the contrary the number of samples investigated or sampled from a study group. N is the number of samples collected and assayed to obtain representative statistical information on the population. The population size defines the upper limit of the statistical sample size.
