What is the Mean?

The mean is a measure of central tendency, which means it is a single value that represents the “average” of a set of data. To calculate the mean, you add up all of the values in the data set and then divide by the number of values. For example, if you have the following data set:

“`
10, 12, 15, 18, 20
“`

The mean would be calculated as follows:

“`
(10 + 12 + 15 + 18 + 20) / 5 = 15
“`

The mean is a useful statistic because it can give you a general idea of what to expect from a data set. For example, if you are trying to determine the average height of a group of people, you could use the mean to get a rough estimate.

The mean is also a good way to compare two or more data sets. For example, if you are trying to determine which of two groups of students scored higher on a test, you could calculate the mean score for each group and then compare the two means.
