Medidas de desempeño en pruebas diagnósticas

Abstract

It is an expository video aimed at presenting, explaining, and illustrating the concepts of sensitivity, specificity, positive predictive value, and negative predictive value using a frequentist approach based on contingency tables. It serves as a supporting resource for the Biostatistics course, taught in the disciplinary stage of the Bioengineering degree program, providing students with the opportunity to review multiple times how these concepts are applied through example-based problem-solving explanations aligned with the course objectives. This helps reinforce their learning, and from a teaching perspective, it facilitates the resolution of questions, since the video presents in a methodical and systematic way the process for formulating and solving the problems.
