What Is Mean?

The mean is a measure of central tendency that represents the average value of a data set. It is calculated by dividing the sum of all values by the number of values in the data set. It is also known as the arithmetic mean or average.

Example: For the data set [1, 3, 3, 6, 7, 8, 9], the mean is (1+3+3+6+7+8+9)/7 = 5.14

Usage: The average is widely used in various fields for summarizing data sets, comparing different groups, or tracking changes over time. However, it can be susceptible to the influence of outliers.
