Midrange
A precise tool.
What is the Midrange & How does it work?
The midrange is a measure of central tendency that lies exactly halfway between the smallest and largest observations in a data set. It provides a quick sense of the data’s spread without being affected by extreme outliers as much as the mean.
Because it only uses the extreme values, the midrange is especially useful in preliminary analyses or when only the range is known. It can also serve as a sanity check for other statistics such as the mean or median.
Mathematically, the midrange is calculated by adding the minimum (a) and maximum (b) values and dividing by two. This simple formula makes it easy to compute by hand or embed in digital calculators.
\frac{a + b}{2}
a = minimum value, b = maximum value

Frequently Asked Questions
How do I calculate the midrange?
To calculate the midrange, add the smallest and largest numbers in your data set and divide by two.
What is the midrange used for?
The midrange provides a quick measure of central tendency and can be useful in preliminary data analysis or when checking other statistics like the mean.
How does the midrange differ from the mean?
Unlike the mean, the midrange is not affected by extreme outliers and only considers the smallest and largest values in the data set.
Can the midrange be used with any type of data?
The midrange is typically used with quantitative data where it makes sense to identify the smallest and largest values.
What are some limitations of using the midrange?
The midrange can be heavily influenced by outliers, so it may not accurately represent the central tendency of skewed distributions.
How do I interpret the midrange value?
The midrange gives you a sense of where the center of your data lies between the minimum and maximum values.
When should I use the midrange instead of other measures like median or mean?
Use the midrange when you need a quick, simple measure of central tendency, especially in small data sets or when preliminary analysis is needed.
