Sensitivity & specificity explained, including positive predictive value & negative predictive value

In this epidemiology tutorial you will learn how to calculate sensitivity and specificity of a diagnostic test. I will also cover positive predictive value (PPV) and negative predictive value (NPV), and the role of prevalence in this context.
