On the other hand, the mean defined in the 11th row was presumably omitted by mistake, since it may also be obtained by applying the seventh mean to the neopythagorean triple 1 / I z i , 1 / I y i , 1 / I x i . (5) the root mean square mean is formed as the geometric mean of the (unweighted) arithmetic mean (1) and the self-weighted arithmetic mean (4): To extend this scheme to include the median, assume that I n i = 2 I k i - 1 is odd and that the xi values have been arranged in increasing order I x i SB [1] sb <= I x i SB [2] sb <= ... I x i SB [ sb SB I n i sb SB ] sb . In much the same way as the arithmetic mean (1) leads naturally to the mean absolute deviation from the arithmetic mean as a measure of dispersion so the median leads naturally to the median absolute deviation from the median.
