Question

ch 8 a student asks each person in one of his classes how many hours, on average, they spend studying each week. this is an example of
convenience sampling.
a double-blind experiment.
a simple random sample.
voluntary response sampling.

Explanation:

• Convenience Sampling: Uses a sample that is easy to access (here, the student's own class, which is convenient to survey).
• Double - blind experiment: Involves neither the participants nor the researchers knowing certain details, not relevant here as it's a survey, not an experiment.
• Simple random sample: Each member of the population has an equal chance of being selected, but here the sample is just the student's class (not randomly selected from a larger population in a simple random way).
• Voluntary response sampling: Depends on people volunteering to respond, but here the student is asking each person in the class (not a voluntary response situation).

So the correct option is the one about convenience sampling.

Answer:

A. convenience sampling.
