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?\n○ systematic random sampling\n○ voluntary sampling\n○ convenience sampling\n○ stratified sampling
Answer
Brief Explanations:
Convenience sampling involves selecting individuals who are easily accessible. The student surveyed members of his own class, which is a convenient group to reach. It is not systematic random sampling (no fixed - interval selection), not voluntary sampling (students didn't choose to be part of the survey on their own initiative), and not stratified sampling (no division of the population into strata).
Answer:
convenience sampling
