Noun The sum of the values of all observations or data points divided by the number of observations. For instance σxsigma sub x-bar is the standard deviation of sample means or standard error of the mean. The central tendency of a collection of numbers which is a sum of the numbers divided by the amount of numbers the collection.

Statistical mean is a certain kind of mathematical average thats very useful in computer science and in machine learning in particular. Statistics Suggest new definition. The terms mean median and mode are used to describe the central tendency of a large data set.
