Question 2 of 5

How do you find the range of a data set?

A. Subtract the smallest value from the largest value
B. Add all the data values together
C. Subtract the smallest value from the average value
D. Add the largest value to the smallest value

Answer 1

The correct Answer is ( option A ).

Explanation:

The range is the easiest measure of variability to calculate. To find the range, follow these steps:

Order all values in your data set from low to high.

Subtract the lowest value from the highest value.

This process is the same regardless of whether your values are positive or negative, or whole numbers or fractions.

Range example:

Your data set is the ages of 8 participants.

Age

37

19

31

29

21

26

33

36

First, order the values from low to high to identify the lowest value (L) and the highest value (H).

Age

19

21

26

29

31

33

36

37

Then subtract the lowest from the highest value.

R = H – L

R = 37 – 19 = 18

The range of our data set is 18 years.
