The book, Adverse Impact Analysis: Understanding Data, Statistics, and Risk, edited by SIOP Fellows Scott Morris and Eric Dunleavy, has been cited as a resource on practical significance in EEO Analysis by the US Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP). The citation is specifically for the chapter written by Fred Oswald, Eric Dunleavy, and Amy Shaw.
As part of its FAQ on the topic, the OFCCP defines practical significance as “whether an observed disparity in employment opportunities or outcomes reflects meaningful harm to the disfavored group,” and acknowledges that practical significance, not just statistical significance, should be considered in compliance reviews. This distinction is important because, as the OFCCP notes, “a virtually unnoticeable disparity in, for instance, selection rates, may nevertheless be statistically significant due to the size of the data set.”
