Correct
Systemic sampling - correct answer Samples are selected at specific, predetermined
intervals. While the interval is predetermined, the start point must be randomized.
Example, when a grocery store gives a survey to every tenth customer
Stratified sampling - correct answer Selecting from different categories within a
population. Used when the characteristics of the population can't be randomly sampled
as a whole. For example, separating a population into subgroups based on race,
