The mode can have several numbers if there are ties, what is that best strategy to take a single number - e.g. take the arithmetic mean or median (of the modes)?
Would the geometric mean, harmonic mean, or any other measure of central tendency be a better option?
Note: Excel has a function Mode.Sngl, although the docs doesn't explain how it works mathematically. Even if it did, I'm not sure it is the best option?
For example, the mode of { 0, 11, 22, 44, 100 } is { 11, 22, 44 }. However, this is not useful for some applications, where a single number must be used. Therefore, 22 could be selected, as the median, or 25.67 as the mean, or a different type of average.
