How to Win Without Overtly Cheating: The Inverse Simpson Paradox

Jerome Percus
New York University

Given two sets of data which lead to similar statistical conclusions, the Simpson Paradox describes the tactic of combining these two sets and achieving the opposite conclusion. Depending upon the given data, this may or may not succeed. Inverse Simpson is a method of decomposing a given set of comparison data into two disjoint sets and achieving the opposite conclusion for each one. This is always possible; however, the statistical significance of the conclusion does depend upon the details of the given data.
