The sample size must be determined in advance to ensure that the sample is representative of the population and that the sample size is sufficient for the statistical analysis. It is not necessary for the sample size to be proportional to the population size, to select members systematically, or to include representation of all major groups within the population, although these may be desirable depending on the specific research question and population of interest.
