The mean is the midpoint of a group of values. It's the average of all of the data's values. In statistics, the mean is the middle value, which is termed as average in mathematics.

The sum of the a sequence of items split by N, where N is the number of entries in the group, is the average in mathematics and statistics. A mean is another name for an average. The average, like the median and mode, is a central tendency, which means it represents a large value in a set.
