How to find the range of a data set

Have you ever found yourself buried in numbers and statistics, perhaps during a school project or while analyzing business data? You’re probably trying to understand how spread out your data is to make more informed decisions. One of the fundamental concepts in statistics that can help you is the range of a data set. In this post, we’ll explore how to find the range easily and why it’s an important measure in understanding your data.

The range of a data set can be found by subtracting the smallest value from the largest value in that set.

To find the range of a data set, start by identifying the smallest and largest numbers within your collected data. Once you have these two values, simply subtract the smallest value from the largest. For example, if your data set consists of the numbers 3, 7, 5, and 2, the largest number is 7 and the smallest is 2. Subtracting these values results in a range of 5 (7 – 2 = 5). This range tells you how wide the data is distributed, providing insight into its variability. Understanding the range is crucial, as it gives you a quick snapshot of your data, helping to inform trends, outliers, and overall patterns that may warrant further investigation.
