Midrange Calculator
Find the midpoint between the minimum and maximum values.
Midrange Formula
Midrange = (minimum + maximum) / 2. It gives the center of a data set based only on its two extreme values.
Midrange vs Mean
The mean uses every value, while the midrange only uses the smallest and largest values, so it can be more sensitive to outliers.
What the Midrange Shows
The midrange is the average of the smallest and largest values in a data set. It gives a quick center estimate based only on the two extremes.
Midrange Example
For values from 10 to 26, the midrange is (10 + 26) / 2 = 18.
When to Use It
Midrange is simple but sensitive to outliers because every result depends entirely on the minimum and maximum. Use median or mean when a more robust summary is needed.
Frequently Asked Questions
Is midrange the same as range?
No. Range is maximum minus minimum.
Can outliers change the midrange?
Yes, substantially.
Does midrange use every data value?
No, only the minimum and maximum.
Methodology, Assumptions and Interpretation
Midrange is (minimum + maximum)/2. Because it depends only on the two extremes, it can change sharply with one outlier and should not be treated as a robust substitute for the median or mean.
