Correlation of arm-span and height in young women of two races.

This paper presents the results of an anthropometric study of 55 black and 74 white females, ages 23-28 years, employed by a state agency in North Carolina. All subjects were measured for height and arm-span. Correlations of the two measures were obtained for each race independently, and differences between the two races were examined. Correlation of arm-span and height for black subjects was 0.776 and for white subjects was 0.894. Analysis of covariance revealed significant (P less than or equal to 0.001) interaction between race and the relationship between arm-span and height.
