Question:
Write the class size and class limits in each of the following:
(i) 104, 114, 124, 134, 144, 154 and 164.
(ii) 47, 52, 57, 62, 67, 72, 78, 82, 87, 92, 97, 102.
(iii) 12.5, 17.5, 22.5, 27.5, 32.5, 37.5, 42.5, 47.5.
Solution:
(i) 104, 114, 124, 134, 144, 154 and 164.
Class size = 114 – 104 = 10
(ii) 47, 52, 57, 62, 67, 72, 78, 82, 87, 92, 97, 102.
Class size = 52 – 47 = 5
(iii) 12.5, 17.5, 22.5, 27.5, 32.5, 37.5, 42.5, 47.5.
Class size = 17.5 - 12.5 = 5
