Correlations for weight, height and two measures of batting performance

The hypothesis that heavier baseball players are better batters was examined in two correlational studies of major league baseball players' performance. Neither height nor weight was significantly correlated with batting average. Both variables correlated significantly and positively with the number of home runs hit by American League players in the 1997 season. After partial correlations were computed, only the correlation between weight and number of home runs hit remained significant.
