mean
[noun]
In statistics, mean commonly refers to the arithmetic mean, also called the average, which is one measure of the mid-point of a dataset. The mean and median approach one another in datasets that approach a normal distribution, but can differ substantially in datasets with skewed distributions. Compare to median. The mean is calculated by obtaining the sum of the values in a dataset and dividing that sum by the number of data points, as in the formulas shown.
