Biostatistics, Scientific research, statistical analysis


Most researchers and students in training are uncertain or confused when they need to conclude their research based on results. However, for many reasons, they address their research questions based mainly on p-values. In this article, we present a framework for decision-making, based on statistical analyses, and describe fundamental aspects of rational decisions. Additionally, we discuss several aspects of the obtainment of scientific evidence, for example, how statistical analyses and research questions are related. Finally, we developed a step-by-step framework for decision-making based on statistical analyses. With this article, we intend to contribute to the development of research, and guide researchers and students regarding this important and neglected subject.
