Block selection involves grouping items together within the population based on certain characteristics, such as geographical location or time period. This method is useful when there are known variations between blocks and you want to ensure a representative sample is taken from each block. Systematic selection involves choosing items at regular intervals, haphazard selection involves choosing items based on convenience, and random selection involves choosing items at random with equal probability of selection. While these methods may also be appropriate in certain situations, none of them specifically involve grouping items together within the population.
