Evidence‑Based Practice (EBP) Practice Test

The purpose statement of a research study is pivotal as it clearly articulates the focus of the research. This statement identifies the population of interest, which defines who or what the research is examining. Additionally, it specifies the relationship between study variables, outlining what the researcher aims to explore or establish through their study. This clarity helps readers understand the intent of the research and sets the foundation for the hypotheses and questions that will be addressed.

Understanding the population and the relationship between variables is essential for framing the study's significance and implications within the broader context of the field. This allows researchers and practitioners to gauge how the findings might be applied or how they contribute to existing knowledge.

The other options do not accurately represent the primary function of a purpose statement. While researcher background, funding sources, and methodology are important components of a research study, they serve different roles within the overall context and structure of the research. The purpose statement is specifically aimed at defining the study's goals and scope, which is why identifying the population and relationships between variables is crucial.
