1) In the case of single measurement which has been made for 3 times replication with 2 levels of the factor of instrument, 4 levels of the factor of subject height, and 3 levels of the factor of individual, it has been cleared that the difference of instruments Aso and Weise has become heighly significant.2) At this actual measurement, the quantity of error in sample mean for Aso is smaller than that for Weise. Accordingly it is needless to say that Aso is more accurate than Weise. Moreover Aso is supposed to be exact, beause of having been smaller in the error variance of sample.3) In the case of 1) the difference among individuals, with α=0.05,has become non significant.4) In consequence of 2 times replication with 4 levels of the factor of subject height and 4 levels of the factor of distance of measuring point, in the case of using Aso and Weis each, the following has been acknowledged. On Aso, both factorial effect of subject height and interaction, with α=0.05,have become significant. On Weise, factorial effects of subject height and the distance of measuring point, and interaction have become non significant with α=0.05.5) In consequence of 3 times replication with 3 levels of the factor of individual, 4 levels of the factor of subject height, on Christen, factorial effects of individual and subject height, with α=0.01,and interaction, with α=0.05,have become significant.
