What Does Range Mean in Math

Introduction:

In math, plenty of terms are available. One of the notable terms in math is the range. Range comprises of several meanings. The meaning of range is the set of all the output values, which are produced by a function. Another common meaning for range is the value that is obtained as a result of maximum and minimum value in a given set of numbers. This article mainly focuses on finding the range value in a given set of numbers. In this article, we are going to discuss the steps involved in finding the range of given set of numbers and few example problems are given based on finding the range value. In addition, few practice problems are given for the students, which helps to understand what does the math term 'range' really meant for.


Step-by-step explanation for finding range in math:


The following steps are essential for finding the range value for given set of numbers.

Step 1: Position the numbers from ascending to descending order.

Step 2: Find the maximum value

Step 3: Find the minimum value

Step 4: Find out the difference between the given maximum and minimum value


Worked examples for finding range in math:


Example 1:

Find the range value for the given set of numbers:

24, 36, 46, 59, 34, 43, 17, 20

Solution:

Maximum value is 59

Minimum value is 17

Range     =  Maximum value - Minimum value

=  59 - 17

=  42

Hence, the range value is 42.

Example 2:

Find the range value for the given data set:

{ 67, 56, 45, 10, 24 }

Solution:

Maximum value is 56

Minimum value is 10

Range     =  Maximum value - Minimum value

=  56 - 10

=  46

Hence, the range value is 46.
