What is the group of people whose issues are included in a research study?

The correct answer is the target population because this term refers to the specific group of individuals whose issues, characteristics, or situations the research study aims to address or understand. Researchers define the target population based on the objectives of the study, which helps in formulating research questions, designing the study, and determining how findings can be generalized.

The target population is crucial for ensuring that the research findings are applicable to the individuals or groups the study intends to benefit or represent. By clearly identifying the target population, researchers can effectively gather relevant data that reflects the experiences or challenges faced by that specific group.

In contrast, the sample population refers to the subset of individuals selected from the larger target population to participate in the study. While the control group is used in experimental research designs to compare outcomes with treatment or intervention groups, it does not encompass the broader issues faced by the entire target population. The volunteer group typically refers to individuals who willingly participate in a study but may not encompass the specific characteristics of the target population. Understanding these distinctions helps clarify why the target population is the most accurate term in this context.
