This analysis examined the linear association between height and weight among U.S. adults using Pearson correlation. Results indicated a moderate positive relationship (r = 0.451), suggesting that taller individuals tend to weigh more. The association was statistically significant (t = 42.618, p < 0.001), and the 95% confidence interval (0.432, 0.469) excluded zero, providing strong evidence against the null hypothesis of no correlation. The coefficient of determination (r² = 0.203) indicates that approximately 20.3% of the variability in one measure is explained by the other, reflecting a meaningful but not complete linear relationship.
