Final answer:
A Retail Audit is the systematic procedure for analyzing a retailer's performance. The department store's survey design is an example of Cluster Sampling. In the grocery store scenario, the population, sample, parameter, statistic, variable, and data are clearly defined in the context of their statistical analysis.
Step-by-step explanation:
A systematic procedure for analyzing the performance of a retailer is known as a Retail Audit. This method involves a comprehensive evaluation of various aspects of a retail business, including its strategies, operations, financial health, compliance with laws and regulations, and customer satisfaction. A Retail Audit gives a complete picture of a retailer's performance relative to the market and to the operational goals of the business.
In the scenario provided, the manager of a department store is measuring employee satisfaction by selecting four departments at random, and conducting interviews with all the employees in those departments. The type of survey design used in this process is Cluster Sampling, as it involves selecting certain groups (or clusters) and then assessing all members within these groups.
Regarding the second example, the grocery store that pulls a sample of 1,000 visits to understand average money spent is engaging in statistical analysis. Here, the population is all the shopping visits, the sample is the 1,000 visits, the parameter is the true average expenditure, the statistic is the calculated average from the sample, the variable is the expenditure on produce per visit, and the data are the actual dollar amounts recorded in the sample.
