How to Find Range in Statistics?
Here’s a step-by-step guide on how to find the range in statistics:
Step 1: Arrange the given values in ascending order. Start by writing down all the values from lowest to highest.
Step 2: Find the highest and lowest values from the dataset.
Step 3: Subtract the lowest value from the highest.
Let’s consider an example for better understanding.
Example: The number of hours spent by employees commuting to work in a week are: 30, 31, 35, 49, 45, 50. Determine the range of commuting hours.
Solution:
Given Dataset: 30, 31, 35, 49, 45, 50
Arrenging the data in ascending order as: 28, 31, 35, 45, 49, 50
Thus, Range = Maximum Value – Minimum Value
⇒ Range = 50 – 28 = 22
Hence, range of the given dataset is 22.

How to Calculate Range
Range is one of the measures of dispersion. It helps us understand how dispersed any dataset is. The range can be calculated using the highest and lowest observations of any dataset. However, while the range offers a simple indication of spread, it may be influenced by outliers, potentially skewing interpretations.
Additionally, in conjunction with other measures of dispersion, such as variance and standard deviation, a more comprehensive understanding of data variability can be obtained. In this article, we will discuss how to calculate the range for any dataset using the formula.
