ANS: A
A research design is the blueprint for conducting a study. It maximizes control over factors that could interfere with the validity of the study findings. Being able to identify the study design and to evaluate design flaws that might threaten the validity of findings is an important part of critically appraising studies. When conducting a study, the research design guides the researcher in planning and implementing a study in a way to achieve accurate results. The control achieved through the quantitative study design increases the probability that the study findings are an accurate reflection of reality.
