Question 12

Stratified sampling method is being used.

The researcher is employing stratified sampling, which involves dividing the population into distinct subgroups (in this case, academic areas) and then sampling independently from each of these groups to ensure representation.

A) Quota

Quota sampling involves selecting a predetermined number of participants from specific subgroups, but it does not require random sampling from each group. Since the researcher is independently sampling from each academic area, this method does not accurately describe the approach used.

B) Judgment

Judgment sampling relies on the researcher’s discretion to select participants based on specific criteria, rather than a systematic method like stratified sampling. In the scenario given, the researcher uses a structured approach that does not align with the subjective nature of judgment sampling.

C) Convenience

Convenience sampling involves selecting individuals who are easiest to reach or sample, without regard for their representation in the population. The researcher’s method of separating students by academic area and sampling each group independently does not fit the convenience sampling model.

D) Stratified

Stratified sampling is characterized by dividing a population into homogeneous subgroups and then conducting independent random samples from each group. This method ensures that each subgroup is represented in the overall sample, which aligns perfectly with the researcher’s approach.

Conclusion

Stratified sampling is the most appropriate term for the method described, as it captures the essence of dividing the population into groups and sampling from each. Other options like quota, judgment, and convenience sampling do not address the systematic and representative nature of the approach taken by the researcher. Thus, D is the definitive answer.
