## Video: Calculate the range (statistics): 4 steps (with pictures)

In statistics, the range stands for the distance between the smallest and the largest value of a data set. The range gives an indication of how far the values spread in a series. If the range is a large number, then the values are widely spread; if it is small, then the values are close together. If you want to know how to calculate the range, follow these steps.

## method

### Step 1. List the values of your data series

To find the range of a data series, you need to list all of the individual elements so that you can determine the highest and lowest values. Write down all of the elements. The elements of our data series are: 24, 19, 20, 14, 24, 25 and 18.

• To determine the highest and lowest value, it can be helpful to enter the values in ascending order: 14, 18, 19, 20, 24, 24, 25.
• Writing down the values in order can also help with other calculations. E.g. when calculating the modal, mean or median value.

### Step 2. Identify the highest and lowest values in the series

In this case, the lowest number is 14 and the highest is 25.

### Step 3. Subtract the lowest number from the highest number

After you've identified them, all you have to do is subtract them from each other. So subtract 14 from 25: 25 - 24 = 11 = the range of the range.
