چکیده
Simpson’s paradox refers to the reversal of a statistical relationship between two variables in sub-populations when the sub-populations are combined and analyzed as a population. This article is intended to provide a broad survey of the past, present and future research surrounding the issue. Real data from a discrimination litigation case is examined to identify the occurrence of the paradox.

The ubiquity of the Simpson’s Paradox
Correspondence: [email protected] Department of Mathematics and Statistics of McMaster University, 1280 Main Street West, Hamilton, (ON) L8S-4K1, Canada Abstract The Simpson’s Paradox is the phenomenon that appears in some datasets, where subgroups with a common trend (say, all negative trend) show the reverse trend when they are aggregated (say, positive trend). Even if this issue has ...
متن کاملComment: Understanding Simpson’s Paradox
I thank the editor, Ronald Christensen, for the opportunity to discuss this important topic and to comment on the article by Armistead. Simpson’s paradox is often presented as a compelling demonstration of why we need statistics education in our schools. It is a reminder of how easy it is to fall into a web of paradoxical conclusions when relying solely on intuition, unaided by rigorous statist...
متن کاملComputational Social Scientist Beware: Simpson's Paradox in Behavioral Data
Observational data about human behavior is often heterogeneous, i.e., generated by subgroups within the population under study that vary in size and behavior. Heterogeneity predisposes analysis to Simpson’s paradox, whereby the trends observed in data that has been aggregated over the entire population may be substantially different from those of the underlying subgroups. I illustrate Simpson’s...
متن کاملUnderstanding Simpson’s Paradox
Simpson’s paradox is often presented as a compelling demonstration of why we need statistics education in our schools. It is a reminder of how easy it is to fall into a web of paradoxical conclusions when relying solely on intuition, unaided by rigorous statistical methods. In recent years, ironically, the paradox assumed an added dimension when educators began using it to demonstrate the limit...
متن کاملSimpson’s paradox, moderation, and the emergence of quadratic relationships in path models: An information systems illustration
While Simpson’s paradox is well-known to statisticians, it seems to have been largely neglected in many applied fields of research, including the field of information systems. This is problematic because of the strange nature of the phenomenon, the wrong conclusions and decisions to which it may lead, and its likely frequency. We discuss Simpson’s paradox and interpret it from the perspective o...
