The range of a data set is the difference between its greatest value and its least value, found by subtracting the least value from the greatest value; it describes how far the data extend from one endpoint to the other. The values may be read from a list, table, picture graph, bar graph, or line plot, using whole-number data appropriate to the context; range is not the same as the greatest value or the number of data points and does not describe every variation within the set.

Detailed Explanation: Find the range
To find the range of a data set:
- Find the greatest value.
- Find the least value.
- Subtract the least value from the greatest value.
Example: The numbers of books five students read are:
- The greatest value is .
- The least value is .
- Subtract:
The range is 4 books. This means the data extend from books to books. The range is not the greatest value, , and it is not the number of students, .
