Midrange Calculator
Calculate the midrange, minimum, maximum, and range of any data set online. Free statistical tool with step-by-step results, bar charts, and pie chart visualization.
About This Calculator
The Midrange Calculator is a free online statistical tool that computes the midrange (mid-extreme) of any comma-separated data set. The midrange is the arithmetic mean of the maximum and minimum values in a data set, making it one of the simplest measures of central tendency. This calculator is ideal for students, teachers, statisticians, and professionals who need a quick central tendency estimate.
The midrange is calculated using the formula: Midrange = (Maximum Value + Minimum Value) / 2. While it is quick to compute, note that the midrange is highly sensitive to outliers since it only considers the two extreme values. For data sets with extreme outliers, consider using the median for a more robust measure of central tendency.
To use the calculator, simply enter your comma-separated numeric values (e.g., 5, 45, 789, 0.5, 0, 25, 1, 12456) and click Calculate. The tool will display the midrange, minimum, maximum, range (max - min), and the total count of values along with interactive bar chart and pie chart visualizations.

Frequently Asked Questions
What is midrange in statistics?
Midrange in statistics is the arithmetic mean of the maximum and minimum values in a data set. It is calculated as (maximum + minimum) / 2 and serves as a simple measure of central tendency.
How do you calculate midrange?
To calculate midrange, find the minimum value and maximum value in your data set, then add them together and divide by two. The formula is midrange = (max + min) / 2.
What is the difference between midrange and range?
Range is the difference between the maximum and minimum values (max - min), while midrange is the average of the maximum and minimum values ((max + min) / 2). Range measures spread, midrange measures central tendency.
Is midrange the same as median?
No, midrange and median are different measures of central tendency. Midrange is the average of the smallest and largest values, while median is the middle value when data is sorted. Median is generally more robust to outliers.
What are the limitations of midrange?
Midrange is highly sensitive to outliers because it only uses the two extreme values. A single extreme value can significantly skew the midrange, making it less reliable than median or mean for data sets with outliers.
Can midrange be used with negative numbers?
Yes, midrange works with negative numbers. The formula (max + min) / 2 handles negative values correctly. For example, data set 20 has min = -10, max = 20, and midrange = (20 + (-10)) / 2 = 5.
How many values do you need to calculate midrange?
You need at least two values to calculate midrange. With a single value, the minimum and maximum are the same, so the midrange equals that value.
What is the midrange used for in real-world applications?
Midrange is used in quality control for quick range checks, in finance to find the midpoint of stock price ranges, in meteorology to report average daily temperatures, and in education for grading curve calculations.
