Step 3: Randomly select clusters to use as your sample. If each cluster is itself a mini-representation of the larger population, randomly selecting and sampling from the clusters allows you to imitate simple random sampling, which in turn supports the validity of your results. Conversely, if the clusters are not representative, then random
Examples For each question below, first decide if the example describes a random sample, second describe why you believe it is/isn't random. Example 1 Several apples are selected from each bin of different types at the market. This is probably not a random sample. The question does not specify how the apples are chosen from each bin.RANDOM SAMPLING AND. RANDOM ASSIGNMENT MADE EASY!
