23. A researcher draws 50 names from a mixed container of name slips representing all the participants at an academic conference. Which type of sampling is implemented in the scenario?
Answer: D
Simple random sampling is implemented in the scenario.
In this scenario, the researcher draws 50 names randomly from a mixed container, which indicates that every participant had an equal chance of being selected. This method exemplifies simple random sampling.
A) Systematic
Systematic sampling involves selecting samples based on a fixed interval from a randomly ordered list. Since the names are drawn directly from a mixed container without any fixed interval or systematic approach, this option is incorrect.
B) Quota
Quota sampling requires the researcher to ensure certain characteristics are represented in the sample, often predetermined by the researcher. In this case, there is no indication that the selection is based on specific quotas; thus, this option is incorrect.
C) Cluster
Cluster sampling involves dividing the population into clusters and then randomly selecting entire clusters for the sample. The scenario describes a direct draw from individual name slips without any clustering, making this option incorrect.
D) Simple random
This option is correct as it accurately describes the method used by the researcher to select names from the container. Each participant had an equal opportunity to be chosen, which is the hallmark of simple random sampling.
Conclusion
The correct answer, simple random sampling, is confirmed by the method used in the scenario, where names are drawn randomly without any systematic or quota-based selection. All other options incorrectly describe different sampling methods that do not apply to the procedure outlined in the question.
