WebApr 24, 2024 · Answer. Geometric mean concentration is used for antibody titers because the titer data usually does not fit a linear scale. When the data is skewed and not normally distributed, it is better to calculate the geometric mean instead of the arithmetic mean, which may not give a good representation of the results. WebApr 23, 2024 · The arithmetic mean of the three logs is (16.2.1) ( 0 + 1 + 2) / 3 = 1 The anti-log of this arithmetic mean of 1 is (16.2.2) 10 1 = 10 which is the geometric mean: (16.2.3) ( 1 × 10 × 100) 0.3333 = 10 Therefore, if the arithmetic means of two sets of log-transformed data are equal, then the geometric means are equal.
