# Range

###### This wiki is incomplete.

Range is the difference between the highest and the lowest observation in a frequency distribution. The formula is almost the same for all types of series.

**Individual Series:**Subtract the lowest from the highest observation.**Discrete Series:**Same as Individual Series. Subtract the lowest from the highest observation. Frequency doesn't matter at all.**Continuous Series:**Range is calculated by taking the difference between the upper limit of the highest class interval and the lower limit of the lowest class interval.

For more information on Statistical Series, see Statistical Series.

## What is the range of the following observation: \[1,2,4,6,8,10,14?\]

Range is the difference between the highest and the lowest observation. Since the highest observation is \(14\) and the lowest observation is \(1\), thus the range is \[14-1=13. \ _\square\]

## What is the range of the values : \[ 20,18,37,42,3,12,15,26?\]

Range is the difference between the highest and the lowest observation. Here, the highest observation \(42\) and the lowest observation is \(3\). Therefore, the range is \[42-3=39. \ _ \square\]
