      We claim that then the optimal value of Q is the arithmetic mean. To prove this, write Q — = (M — Xi) + (Q — M) where Q is any value we accept for our measurement, and M is the arithmetic mean of the observed values. Then (Q - = (M - + (Q - + - - M) . Summing these equations, we note that the last terms sum to O, because

      By the Geometric Mean (Altitude) Theorem the altitude drawn to the hypotenuse of a right triangle separates the hypotenuse into two segments. The length of this altitude is the geometric mean between the lengths of these two segments. So, the total height of the statue is about 159 + 68 or 227 inches, which is equivalent to 18 ft 11 in.

      The calculation of the Geometric Mean may appear impossible if one or more of the data points is zero (0). In these cases, however, the convention used is that a value of either '1', one half the limit of detection, or some other substitution is allowed for each zero or "less than" value, so that the information contained in these data is not lost.
