Range vs Maximum Value
Formula
## How to Calculate the Range ### Formula **Range = Maximum Value - Minimum Value** The range is the simplest measure of spread. It tells you the total span of the data but is highly sensitive to outliers because it depends only on the two most extreme observations. ### Midrange The midrange is the average of the maximum and minimum: **(Max + Min) / 2**. It estimates the center of the data using only the extremes.
Esempio Risolto
A dataset has a maximum of 95 and a minimum of 22. Find the range.
- 01Range = 95 - 22 = 73
- 02Midrange = (95 + 22) / 2 = 58.5
Domande Frequenti
Why is the range not a reliable measure of spread?
It uses only two data points (max and min), so a single outlier can inflate it dramatically. The interquartile range or standard deviation use more of the data.
Can the range be negative?
No. The maximum is always greater than or equal to the minimum, so the range is always zero or positive.
When is the range useful?
It provides a quick sense of variability for small, well-behaved datasets and is commonly used in quality control (e.g., R-charts in manufacturing).
