**Definition of Measure of Variation**

- Measure of variation is a measure that describes how spread out or scattered a set of data. It is also known as measures of dispersion or measures of spread.

**Examples of Measure of Variation**

**Solved Example on Measure of Variation**

The heights in cm of ten students are: 157, 152, 165, 151, 160, 156, 155, 162, 158, 163. Find the range of the data.

Choices:

A. 10

B. 13

C. 15

D. 14

Correct Answer: D

Solution:

Step 1:Maximum height = 165.

Step 2:Minimum height = 151.

Step 3:Range = 165 - 151 = 14. [Range = maximum height - minimum height.]
