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 element from a list. The student didn’t do this.
• Voluntary sampling: Relies on people volunteering to participate. The student surveyed his class, not volunteers.
• Convenience sampling: Uses participants who are easily accessible. The student surveyed his own class (easily available), so this fits.
• Stratified sampling: Divides the population into strata and samples from each. The student didn’t stratify.

Answer:

C. convenience sampling
