Question

tell whether the situation describes a voluntary sample, convenience sample, or neither.

Explanation:

Analyze the sampling scenario

Using the Sampling Methods knowledge point

The researcher chooses a location (a local mall) specifically because it is close to their house. This selection is based on ease of access and proximity, rather than a random selection process.

Define convenience sampling

A convenience sample consists of members of a population who are easy to reach or readily available to the researcher. Selecting a mall because of its close proximity to the researcher's home is a classic example of choosing a sample based on ease of access.

Define voluntary response sampling

A voluntary response sample consists of people who self-select or choose themselves to respond to a general appeal (such as an online poll or a call-in radio show). While the researcher is interviewing people at the mall, the primary method of selecting the location itself is based on convenience. Therefore, the situation is best described as a convenience sample.

A researcher interviews shoppers at a local mall. The mall was chosen because it was close to the researcher's house.
