Understanding the Range- How to Determine the Extent of Variability in a Data Set

What is the Range in a Data Set?

The range in a data set is a fundamental statistical measure that provides insight into the spread of the data. It is defined as the difference between the highest and lowest values in the data set. Understanding the range is crucial for analyzing the variability and distribution of data, as it offers a quick overview of the data’s spread without delving into more complex statistical measures. This article aims to explore what the range is, how it is calculated, and its significance in data analysis.

In the following paragraphs, we will delve into the definition of the range, its calculation, and its applications in various fields. Additionally, we will discuss the limitations of using the range as a sole measure of data variability and suggest alternative methods for a more comprehensive analysis.
