Range — A Measure of Spread

Lets see how scattered our data is ?

The range is a simple measure of spread or dispersion in statistics, representing the difference between the maximum and minimum values in a dataset. It provides an indication of how spread out the values are.

Before we dive in I highly recommend to read these:-

• Statistics — Its all about reliability !!
• Mean — The Average, my best guess of all time !!
• Median — The Middle Most Term
• Mode: The Most Frequent & Common Term in Stats

How to Calculate the Range

1. Identify the Maximum Value: Find the highest value in the dataset.
2. Identify the Minimum Value: Find the lowest value in the dataset.
3. Subtract the Minimum from the Maximum: The range is the result of this subtraction.

Range=Maximum Value−Minimum Value

Example:-

Let’s Consider the following dataset: 3,7,8,15,203, 7, 8, 15, 203,7,8,15,20

1. Maximum Value: 20
2. Minimum Value: 3
