Question

Quizplus · Accepted Answer

The first decision for selecting subjects for an experiment is deciding on the target population, which involves identifying the characteristics and parameters of the group of individuals that the researcher wants to generalize the results to. Once the target population is identified, the researcher can develop a sampling plan to select a representative sample from that population. Therefore, option B is the best choice. Option A is not the first decision as it follows after the target population has been selected. Options C and D refer to threats to validity that should be considered during the design and analysis of an experiment, but they do not relate to the first decision in selecting the subjects.
