Question

a high school student volunteers to present a report to the administration about the types of lunches students prefer. he surveys members of his class and records their choices. what type of sampling did the student use?

○ systematic random sampling
○ voluntary sampling
○ convenience sampling
○ stratified sampling

Explanation:

To determine the sampling type, we analyze each option:

• Systematic random sampling: Involves selecting every nth individual, which is not the case here.
• Voluntary sampling: Relies on people volunteering to participate, but the student surveyed his class (not volunteers).
• Convenience sampling: Uses readily available individuals (his class is convenient to survey).
• Stratified sampling: Divides the population into strata and samples from each, which is not done here.

The student surveyed his own class (easily accessible), so it's convenience sampling.

Answer:

C. convenience sampling
