Definition of Range (Statistics)

The range of a data set is the difference between its highest and lowest values.

For example, the lowest value of the data set \(\{2,3,7,9,1,4\}\) is \(1\) and its highest value is \(9\), so its range is \(9 - 1 = 8\).

The highest value on the dot plot is \(8\) and the lowest value is \(4\), so the range of the data set represented by the dot plot is \(8 - 4 = 4\).


The aim of this dictionary is to provide definitions to common mathematical terms. Students learn a new math skill every week at school, sometimes just before they start a new skill, if they want to look at what a specific term means, this is where this dictionary will become handy and a go-to guide for a student.
