A research design typically outlines the theories and models underlying a project; the research question(s) of a project; a strategy for gathering data and information; and a strategy for producing answers from the data. [1] A strong research design yields valid answers to research questions while weak designs yield unreliable, imprecise or ...
Also, the study must be conducted using best available research methods. Question 2 measures the reliability of the study. If it is an intervention study, reliability consists of: whether the intervention worked, how large the effect was, and whether a clinician could repeat the study with similar results.
