To find the range of a data set, start by listing the set of numbers in order from smallest to largest. Then, take the smallest number in the list and subtract it from the largest number to find the range.
The range is the easiest measure of variability to calculate. To find the range, follow these steps: Order all values in your data set from low to high. Subtract the lowest value from the highest value. This process is the same regardless of whether your values are positive or negative, or whole numbers or fractions.
The range is the easiest measure of dispersion to calculate and interpret in statistics, but it has some limitations. In this post, I’ll show you how to find the range mathematically and graphically, interpret it, explain its limitations, and clarify when to use it.
To calculate range, list all of the numbers in your data set in order. Then, identify the highest and lowest numbers in the set. For instance, if your data set consists of the numbers 23, 40, 57, and 95, then your lowest number would be 23, and the highest would be 95.

The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6. It is that simple! But perhaps too simple ... The Range Can Be Misleading. The range can sometimes be misleading when there are extremely high or low values.
The range is the easiest measure of variability to calculate and interpret. Say, for example, we have a data set of 20, 30, 35, 36, 40, 50, 51. The range is 30. The range can be measured if given ungrouped data, frequency distribution table, graphs such as histogram, boxplot, and scatterplots.
The formula to calculate the range of a data set is given below: Range = Maximum value – Minimum value However, we can define the formulas to find the range of grouped and ungrouped data.
The range of a data set is the difference between the largest and smallest values: r a n g e l a r g e s t d a t a v a l u e s m a l l e s t d a t a v a l u e = −. The range gives us an indication as to how spread out the data is; it is the maximum difference between elements in the data set.
