CORRELATION AMONG PHYSICAL MEASURES APPLICABLE IN HUMAN ENGINEERING

Abstract

By using the previously reported various kinds of measured values on human bodies from the view points of human engineering, which values had been obtained by measuring 41 items representing various parts of a body of Japanese young and middle aged men, the correlation coefficients between each of five basic measured values, i.e., those of body height, body weight, chest girth, sitting height, and buttock leg length, and each of measured values of other 40 items were determined, and were viewed from various different angles. The main results are summarized as follows. 1) The correlation between each of measured values of body height, body weight, chest girth, sitting height, and buttock-leg length, and each of other measures were calculated and the significance of the correlation coefficients was studied. 2) The difference between these correlation coefficients was tested and these correlation coefficients were classified into those having higher correlation and lower correlation. 3) The results showed high correlation between measures in lengths and between measures in widths. 4) Head length, interpupil distance, first finger length, medical malleolus height, etc., did not show any significant correlation with each of body height, body weight, chest girth, sitting height, and buttock-leg height. 5) High correlation coefficients between body height and measures in length was observed, especially in the age group of thirties, but lower in forties. 6) A linear regression equation by which other measured values might be inferred from the values of body height, body weight, chest girth, sitting height, and buttock-leg length was determined and shown.
