An average in statistics. (See under “Physical Sciences and Mathematics.”)
In statistics, an average of a group of numbers or data points. With a group of numbers, the mean is obtained by adding them and dividing by the number of numbers in the group. Thus the mean of five, seven, and twelve is eight (twenty-four divided by three). (Compare median and mode.)
