Midrange Calculator
The midrange is the average of the minimum and maximum values in a dataset, representing the midpoint between the two extremes. This calculator computes the midrange and also shows the mean, median, and range for comparison. The midrange is a simple measure of central tendency that is easy to calculate and understand, though it is sensitive to outliers because it depends only on the two extreme values. Use this calculator to quickly assess the middle of your data's range and to compare it with other measures of central tendency.
Midrange formula
Midrange = (Maximum + Minimum) / 2
Range = Maximum - Minimum
Mean = Sum of all values / Count
Median = Middle value (when sorted)
Understanding central tendency measures
- Midrange: Simple average of extremes. Sensitive to outliers. Best for quick estimates.
- Mean: Average of all values. Sensitive to outliers. Most common measure.
- Median: Middle value when sorted. Robust to outliers. Good for skewed data.
- When midrange equals mean and median: Your data is symmetrically distributed.
- When they differ: Your data is skewed or has an irregular shape.
Midrange calculator: frequently asked questions
What is the midrange?
The midrange is the average of the minimum and maximum values in a dataset: Midrange = (Max + Min) / 2. It is a simple measure of central tendency and represents the midpoint between the two extreme values.
How is the midrange different from the mean and median?
The mean is the average of all values. The median is the middle value when sorted. The midrange is the average of only the two extreme values. The midrange is sensitive to outliers because it uses only the minimum and maximum.
When is the midrange useful?
The midrange is useful as a quick estimate of central tendency for small datasets or uniform distributions. It is simple to calculate and understand. However, it is not robust to outliers and is not commonly used in advanced statistics.
Is the midrange always between the median and mean?
Not necessarily. The midrange depends only on the extreme values. For symmetric distributions, the midrange often equals the median and mean. For skewed data, the midrange can be higher or lower depending on where the extremes lie.
What is the relationship between midrange and range?
The range is the difference between max and min: Range = Max - Min. The midrange is the midpoint: Midrange = (Max + Min) / 2. Together, they describe the spread and center of the extremes in your data.
