Subject 4. Measures of Center Tendency , therefore, is not recommended for use as the only measure of central tendency. A further disadvantage of the mode is that many distributions have more than one mode. These distributions are called "multimodal."

The harmonic mean of n numbers x i (where i = 1, 2, ..., n) is:
The special cases of n = 2 and n = 3 are given by:
and so on.
For n = 2, the harmonic mean is related to arithmetic mean A and geometric mean G by:
The mean, median, and mode are equal in symmetric distributions. The mean is higher than the median in positively skewed distributions and lower than the median in negatively skewed dist
