A mean is a numeric quantity representing the "center" of a collection of numbers or the number that you can replace all the numbers in a data set by to still achieve the same total (the total is not necessarily the sum). [1] . There are several kinds of means (or "measures of central tendency ") in mathematics, especially in statistics.

Mean, median, and mode are measures of central tendency used in statistics to summarize a set of data. Mean (x̅ or μ): The mean, or arithmetic average, is calculated by summing all the values in a dataset and dividing by the total number of values.

The mean, commonly known as the arithmetic average, is one of the most fundamental concepts in statistics. As a measure of central tendency, it answers the question, where do most values fall? In statistics, we work with population and sample means, each having its own symbol and formula.

In statistics, the mean is important for the following reasons: 1. The mean gives us an idea of where the “center” of a dataset is located. 2. Because of how it’s calculated, the mean carries a piece of information from every observation in a dataset. The following example illustrates both of these reasons.
