Final answer:
The correct term to describe the main parts of a retail strategy is 'Core'. The question involves selecting clusters (entire departments) and surveying all members within, thus the type of survey design used is Cluster sampling. The correct answer is B.
Step-by-step explanation:
The core parts of a retail strategy are broken down into these basic categories: choosing a store location, managing a business, merchandise management and pricing, and communicating with the customer.
Survey Design Type
The manager of a department store decides to measure employee satisfaction by selecting four departments at random, and conducting interviews with all the employees in those four departments.
In this case, the manager of the department store is selecting four departments at random, which represents different strata. By interviewing all the employees in those four departments, the manager is ensuring representation from each stratum, allowing for more accurate results.
This type of survey design is known as Cluster sampling because it involves selecting certain groups (or clusters) and then surveying every member within those groups. In this case, the entire departments are the clusters that have been randomly selected. The correct answer is B.
