Question

Find the value of range for the following Data 7, 9, 6, 8, 11, 10, 4
5
7
8
9

Answer 1

Answer:

Correct answer 13  

Explanation:

The range is the difference between the smallest value and largest value of the data set.

Given data set is 7,9,7,5,9,9,18,6,8,9

The smallest value in the given data is 5 and

the largest value is 18

Therefore the range is 18−5=13

Answer 2

Given:

The distribution - 7, 9, 6, 8, 11, 10, 4

To find:

The range of the distribution

Solution:

Since, the distribution is 7, 9, 6, 8, 11, 10, 4

Arranging it in ascending order -

= 4,6,7,8,9,10,11

Thus,

Lowest Value = 4

Highest Value = 11

Using the formula to calculate Range -

Range = Highest Value - Lowest Value

Substituting the values -

= 11 - 4

= 7

Answer: The range of the distribution is 7.
