Coefficient Of Range Calculator


Calculating the coefficient of range can provide valuable insights into the spread or dispersion of a dataset. It’s a statistical measure that indicates the relative variability of data points within a set. This article will guide you through the process of using a calculator to determine the coefficient of range, providing clarity on its formula, usage, and practical examples.

How to Use

To utilize the coefficient of range calculator effectively, follow these steps:

  1. Enter the dataset values into the input fields.
  2. Click the “Calculate” button to generate the coefficient of range.
  3. Review the result provided.


The coefficient of range (CR) is calculated using the following formula:


  • Xmax​ is the maximum value in the dataset.
  • Xmin​ is the minimum value in the dataset.

Example Solve

Let’s consider a dataset: 12, 25, 36, 48, 51.


What is the significance of the coefficient of range?

The coefficient of range helps in understanding the variability of data points within a dataset. A higher coefficient indicates greater variability.

Can the coefficient of range be negative?

No, the coefficient of range is always a non-negative value since it’s a measure of relative variability.

Is the coefficient of range affected by outliers?

Yes, outliers can impact the coefficient of range, especially if they are extreme values that significantly affect the range.


The coefficient of range serves as a useful tool for analyzing the variability within a dataset. By understanding its formula and utilizing a calculator, users can gain valuable insights into the spread of their data. Whether for statistical analysis or decision-making processes, the coefficient of range provides valuable information for researchers and analysts.
