## How to Calculate the Range ### Formula **Range = Maximum Value - Minimum Value** The range is the simplest measure of spread in a data set. It tells you the total span of your data. The **midrange** is the average of the minimum and maximum: (min + max) / 2.
计算示例
Find the range of the values 15, 28, 7, and 42.
- 01Minimum = 7
- 02Maximum = 42
- 03Range = 42 - 7 = 35
- 04Midrange = (7 + 42) / 2 = 24.5
常见问题
What is the range in statistics?
The range is the difference between the highest and lowest values in a data set. It provides a quick measure of how spread out the data is.
What are the limitations of the range?
The range only considers the two extreme values and ignores the distribution of all other data points. It is sensitive to outliers. Standard deviation is usually a more informative measure of spread.
