Bayes’ Theorem Explained: Why a 99% Accurate Test Can Still Be Wrong

Infographic explaining Bayes’ theorem showing why a 99 percent accurate test can result in only a 50 percent probability

Statistics surround us every day. We encounter percentages, probabilities, survey results, economic indicators, and medical studies in news reports, social media posts, advertisements, and political debates. Because numbers appear objective and scientific, many people accept them without questioning what they actually mean. However, statistics can be surprisingly misleading when presented without context. A single percentage … Read more
