No answer provided yet.Well, you can always calculate the mean on a set of data. The mean is a measure of the center or the population. If the data-set is highly skewed, say it contains a handful of very large values, the mean will be pulled by these values and no-longer be an accurate representation of the center.
For example, if you wanted to find the mean salary of employees at a company, the mean will be heaviliy skewed by the CEO's salary. In such situations, the median or the geometric mean (the anti-log of the mean of the log-transformed data) will be a better indication of the average employee salary.
