Question

Rearrange the following raw data in descending order:

5.3, 5.2, 5.1, 5.7, 5.6, 6.0, 5.5, 5.9, 5.8, 6.1, 5.5, 5.8, 5.7, 5.9 and 5.4. Then write the:

(i) highest value

(ii) lowest value

(iii) range of values

Answer 1

Writing these numbers in descending order we get:

6.1, 6.0, 5.9, 5.9, 5.8, 5.8, 5.7, 5.7, 5.6, 5.5, 5.5, 5.4, 5.3, 5.2, 5.1

(i) Highest value = 6.1

(ii) Lowest value = 5.1

(iii) Range of values = Highest value – lowest value

= 6.1 - 5.1 = 1.0
