Block selection involves the grouping of items within the population and selecting a sample from each group. This method is useful when the items in the groups are similar or have some sort of relationship to each other. Haphazard selection relies on the personal judgment of the selector and may not be representative of the population, random selection may not take into account any natural groupings that exist, and systematic selection may introduce bias if a pattern exists in the population.
