Write the class-size in each of the following:
(i) 0-4, 5-9, 10-14
(ii) 10-19, 20-29, 30-39
(iii) 100-120, 120-140, 160-180
(iv) 0-0.25, 0.25-0.50, 0.50-0.75
(v) 5-5.01, 5.01-5.02, 5.02-5.03
(i) Class size = Upper limit – Lower limit
= 4 – 0 = 4
(ii) Class size = Upper limit – Lower limit
= 19 – 10 = 9
(iii) Class size = Upper limit – Lower limit
= 120 – 100 = 20
(iv) Class size = Upper limit – Lower limit
= 0.25 – 0 = 0.25
(v) Class size = Upper limit – Lower limit
= 5.01 – 5 = 0.01
