Reviewing the Literature, Developing a Hypothesis, Study Design

  • C. Max Schmidt
Chapter

Abstract

Rigorous research investigation requires a thorough review of the literature on the topic of interest. This promotes development of an original, relevant, and feasible hypothesis. Design of an optimal study to test the hypothesis then requires adequate power, freedom from bias, and conduct within a reasonable timeframe with resources available to the investigator.
