Abstract
—This research project investigates whether there is a significant difference in the average age of death between left-handers and right-handers by analyzing age distribution data collected from a National Geographic survey. Utilizing Bayesian statistics and data visualization techniques, the study calculates the probability of being a specific age at death based on handedness. The results reveal that there is insufficient evidence to support the claim that left-handers experience an earlier average age of death, challenging a commonly held belief. This evidence-based analysis contributes valuable insights to the discussion on handedness and longevity, highlighting the importance of rigorous data-driven research in dispelling prevailing myths.
