Stratified random sampling first divides the population into subgroups based on one or more variables of interest, and then randomly selects participants from each subgroup to ensure representation from all subgroups in the sample. Simple statistical sampling does not involve subgroups, systematic random sampling selects every nth participant, and systematic density sampling involves selecting participants based on their spatial proximity.
