The representativeness of a sample affects the ability to generalize experimental findings to a larger population. If the sample is not representative of the population, then the findings may not apply to the larger population, reducing the external validity of the study. It does not directly affect the experimental design, internal validity, or the statistical analysis of the data, although these factors may be indirectly affected by a poor sample selection.
