The remainder of this book will attempt to sketch some basic structures typically introduced in the required graduate statistics sequence in the behavioral sciences, along with some necessary cautionary comments on usage and interpretation. The purpose is to provide a small part of the formal scaffolding needed in reasoning ethically about what we see in the course of our careers, both in our own work and that of others, or what might be expected of a statistically literate populace generally. Armed with this deeper understanding, graduates can be expected to deal more effectively with whatever ethically charged situations they might face.
If a calculation is repeated several times, the value accepted is that which occurs most often, not the median, mean, or any other figure. Even in these cases, a majority, or some more overwhelming preponderance, rather than merely a mode, is usually required for a satisfactory decision. 2 A current discussion of yet another attempt to use statistical models to infer causality from observational data is in the article by Gina Kolata, “Catching Obesity From Friends May Not Be So Easy” (New York Times, August 8, 2011).
A general example might help show the importance of Bayes’ rule in assessing the value of screening for the occurrence of rare events: Suppose we have a test that assesses some relatively rare occurrence (for example, disease, ability, talent, terrorism propensity, drug or steroid usage, antibody presence, being a liar [where the test is a polygraph], or fetal hemoglobin). ” Two “reliabilities” are needed: (a) the probability, P (B|A), that the test is positive if the person has “it”; this is referred to as the sensitivity of the test; ¯ A), ¯ that the test is negative if the (b) the probability, P (B| person doesn’t have “it”; this is the specificity of the test.
