In hypothesis testing, a p-value can indicate how statistically significant a particular set of findings are. But there are some concerns that researchers have become overly reliant on the measure, leading to a lack of nuance in some discussions of data, or they are discarding interesting work simply because the p-value isn't on the right side of point 0.05. The debate over p-values is the focus of a special issue of The American Statistician and this episode of Stats and Stories. Rosemary Pennington is joined by regular panelists John Bailer, chair of Miami’s Statistics Department and Richard Campbell former and founding chair of Media Journalism and Film. Their guest Nicole Lazar, a professor of statistics at the University of Georgia. She also recently edited with Ron Wasserstein and Allen Schirm, special issue of the American statistician which included 43 wide ranging articles focused on p-values, contextualizing their history, their use as well as the debate around their utility and usefulness.
