Question

Using the following data, construct a frequency distribution table:

46, 44, 42, 54, 52, 60, 50, 58, 56, 62, 50, 56, 54, 58 and 48.

Now answer the following:

1. What is the range of the numbers?
2. How many numbers are greater than 50?
3. How many numbers are between 40 and 50?

Answer 1

Marks	Tally marks	Frequency
42	|	1
44	|	1
46	|	1
48	|	1
50	||	2
52	|	1
54	||	2
56	||	2
58	||	2
60	|	1
62	|	1
Total		15

(i) Range of numbers = Highest number – Lowest number

= 62 – 42 = 20

(ii) 9 numbers are greater than 50

(iii) 6 numbers are between 40 and 50
