Pearce wants to conduct a survey of shoppers at the local mall. He obtains a list of the major stores, restaurants, and other establishments and creates the following table that includes each destination’s name, location (zone), category, and category rank. The category rank represents where the mall destination falls in a list of all the establishments in the same category; for example, Aéropostale is second in the list of clothing stores, so its category rank is 2.
Use the table and two methods to choose a cluster sample of 5 establishments at which Pearce can interview shoppers.
- Method 1: Give each zone an equal chance of selection.
- Method 2: Give each establishment an equal chance of selection.
