16 hours ago
- Henley Royal Regatta's historic data shows Berkshire station wins 53.5% of 7555 races, far above the expected 50% for equal stations.
- Statistical analysis confirms the Berkshire station provides a real advantage, as the deviation exceeds 1.645 standard deviations.
- Men's win rate from Berkshire (53.7%) vs women's (52.7%) is not statistically significant, with a chi-squared test yielding a p-value > 0.12.
- A refined chi-squared test comparing heats vs advanced rounds shows significance (p < 0.05), suggesting skill amplifies the Berkshire advantage.
- The Berkshire advantage may be due to wake flow disturbances affecting the Buckinghamshire station more.
- The author warns against p-hacking by regrouping data post-hoc to achieve significance.
