Question

a company wants to administer a satisfaction survey to its current customers. using their customer database, the company randomly selects 100 customers and asks them about their level of satisfaction with the company.

what type of sampling method is used?

Explanation:

Analyze the sampling scenario

The problem describes a company that wants to survey its current customers.
The company uses its customer database (which represents the entire population of current customers) and randomly selects 100 customers from it. Every customer in the database has an equal chance of being selected, and any group of 100 customers has an equal chance of being chosen.

Identify the sampling method

Using the Sampling Methods knowledge point, we evaluate the characteristics of this selection process:

• It is not systematic because there is no fixed interval (like choosing every \(k\)-th customer).
• It is not stratified or cluster-based because the population is not divided into subgroups before selection.
• It is not convenience or voluntary response because the selection is done randomly from the complete database.
• Since 100 individuals are chosen completely at random from the entire population, this is a simple random sampling (or simple random sample) method.
