How to Use the Midrange Calculator
This midrange calculator helps you find the midpoint between the smallest and largest values in a dataset.
To use the calculator:
- Enter your data values in the input field. You can seperate values either by commas, spaces, tabs, or line breaks. The tool also allow you to copy-paste values directly from Excel, Google Sheet, or text documents.
- Click Calculate.
The calculator will instantly return the midrange and show you exactly how to find the value manually, using a step-by-step approach. This approach is meant to ensure that you not only get the answer but also learn how to compute midrange using your own data.
What Is Midrange?
Midrange is a statistical measure of central tendency, which is computed by finding the average of the minimum and maximum value in a dataset. Unlike the range, which is a measure of dispersion, midrange is considered a measure of central tendency because it provides a quick, simple estimate of the “center” of a dataset by averaging the highest and lowest values.
Midrange Formula
The midrange formula is: Midrange = (Maximum + Minimum) / 2
Where:
- Maximum is the largest value in the dataset.
- Minimum is the smallest value in the dataset.
How to Calculate Midrange
To calculate the midrange manually:
- Arrange the dataset from the smallest to the largest
- Identify the minimum and Maximum value in the dataset.
- Apply the midrange formula by adding the minimum and maximum and dividing the results by 2.
Example
A researcher records the following waiting times, in minutes:
29, 40, 12, 15, 18, 22, 30, 35
Find the midrange.
Solution
To find the midrange by hand, follow these steps:
Step 1: Arrange the dataset in ascending order
The ordered data is: 12, 15, 18, 22, 29, 30, 35, 40
Step 2: Identify the maximum and minimum values in the dataset.
From the dataset:
- Maximum = 40
- Minimum = 12
Step 3: Apply midrange formula.
By definition: Midrange = (Maximum + Minimum) / 2
Substituting the values into the formula and solving, we get:
Midrange = (40 + 12) / 2
= 52 / 2
= 26
Therefore, the midrange is 26 minutes, This implies that 26 is the midpoint between the smallest and largest waiting times in the dataset.
Midrange vs Range
Midrange and range both use the minimum and maximum values in their calculations. However, they describe different things.
The midrange is a measure of center because it finds the midpoint between the smallest and largest values. On the other hand, the range is a measure of spread because it finds the distance between the smallest and largest values.

Frequently Asked Questions
This calculator finds the midrange of a dataset. It identifies the minimum and maximum values, then calculates the midpoint between them.
The midrange formula is: Midrange = (Maximum + Minimum) / 2
No. The range measures the distance between the maximum and minimum values, whereas the midrange measures the midpoint between the maximum and minimum values.
Yes. Midrange is a simple measure of center because it gives the midpoint between the smallest and largest values.
Yes. Since the midrange uses only the minimum and maximum values, an outlier can strongly affect the result.
Use the midrange when you need a quick midpoint between the smallest and largest values, or when a question specifically asks for it.
