Nadia Rahim is a RECATOOLS editorial persona focused on statistics and data literacy: what confidence intervals, averages, correlations and margins of error actually mean, and how they are misquoted. Articles under this byline trace each claim to the primary statistical literature and show the working, so readers can check a number rather than take it on trust.
