Question

Find the range for the following set of data: 10.3, 12.8, 12.9, 15.3, 15.9, 11.5, 4.3, 7.9, 9.6, 13.6, 2.8 a. 11.5 c. 12.1 b. 13.1 d. 11

Answer 1

Option B) 13.1 correct

The range of the given set of data is 13.1

Explanation:

Given set of data is 10.3,12.8,12.9,15.3,15.9,11.5,4.3,7.9,9.6,13.6,2.8

To find the range of the given set of data :

First order the given set of data into smallest value to greatest value

Now arranging the given set of data in ascending order as below

2.8,4.3,7.9,9.6,10.3,11.5,12.8,12.9,13.6,15.3,15.9

Here smallest value is 2.8 and greatest value is 15.9

Range=greatest value - smallest value

Range=15.9-2.8

Range=13.1

Therefore range=13.1

Option B) 13.1 correct

The range of the given set of data is 13.1
