Fig. 1. Tolerance ellipses for Korean men. The centers are 306.3 Ω /m and 34.9 Ω /m. The slopes of the major and minor axes are 42.5° and −89.5° on this scale of the RXc graph, respectively. The outer black elliptical line, the middle blue line, and the inner red line indicate the 95%, 75%, and 50% tolerance ellipses, respectively. The lengths of the semi-major and minor axes are 85.1 Ω/m and 7.0 Ω/m for the 95% tolerance, 57.9 Ω/m and 4.8 Ω/m for the 75% tolerance, and 41.0 Ω/m and 3.4 Ω/m for the 50% tolerance ellipses, respectively.

R/H = resistance normalized by height, Xc/H = reactance normalized by height, R = resistance, Xc = reactance.
