## More About this Sample Range Calculator

The sample range corresponds to the difference between the maximum and minimum value of a sample. It is used as a measure of dispersion of a distribution, but not too frequently.

### What is the Range formula?

The sample range is computed as Range = Max - Min. For example, if you have a sample data: 3, 1, 4, 5, 6, 7, 10, 12, 13, 1, 24, 24, the range is Max - Min = 24 - 1 = 23. You can try our descriptive statistics calculator in case that you need to get a more complete calculation of ALL of the most common descriptive statistics, including mean, SD and quartiles.

### Why do I need to compute the range?

The range is an integral part of the set of descriptive statistics that are typically reported. Why would you use the range?

- It is a measure of dispersion: A large range indicates that the difference between minimum and maximum is large, suggesting some degree of dispersion
- It gives you the size of the whole spectrum of values of the data (at least for the given sample)
- If you don't have the standard deviation provided, you can use the range rule of thumb to estimate the standard deviation

### Is the range the same as the midrange?

No, they are tightly related, but they are not the same. The range is the *difference* between the minimum and maximum
points of a sample, whereas to calculate the midrange, you need the *average* of the
minimum and the maximum.
