You may calculate range across data sets for potential data patterns. There are several reasons you might want to determine statistical range, including: Searching for patterns The company used this software for four years and paid annual prices of $650, $700, $850 and $900 respectively to continue using the software. ![]() This can help determine how significantly the price has increased over time. The company's financial analyst gathers the payment amounts spent to renew the software membership each year.

You can refer to this range when using it in later equations. If you want to use the range for other equations, write it down in a clear, unmarked area of your notebook or computer that's easy to find. You can apply range when determining other factors like mean and mode. Once you have finished your equation, you have your range. Related: How To Find Range (With Tips and Examples) 3. Highest value - lowest value = range (H - L = R)įor this example, the equation is 509 - 12.5 = 496.5 You can now subtract these two values from each other to determine the overall range. Continuing with our earlier example, the data's lowest value is 12.5 and the highest is 509. These two values are the most important elements of the formula and help us best understand the difference between the numbers in the data set. Since our numbers are now in ascending order, we can easily identify the smallest and largest numbers in the equation. Find the lowest and highest numbers, then subtract the smallest Related: What Is a Salary Range and How Do Employers Use It? 2. This allows you to gain a better understanding of how your values differ from each other and makes it easier to locate the smallest and largest numbers in your set.įor example, if you had a data set with the numbers: Once you have all your numbers together, you can order them from lowest to highest. Gather the numbers you want to calculate within your data set and write them out. Arrange data set numbers from low to high Follow these steps to calculate the range: 1. The simplest way to calculate the data set is the range formula. There are several ways to calculate the range of the data set.

A lower number means the values are all closer to range and amount. For example, if the range is incredibly high, then the numbers are spread out and differ significantly. This helps them understand how different the numbers are within the set, helping them make critical business decisions. ![]() ![]() Statistical range is the calculation that statisticians, mathematicians and analysts may use to find the difference between the highest and lowest variables in a data set.
