Question

Given below are heights of 15 boys of a class measured in cm:

128, 144, 146, 143, 136, 142, 138, 129, 140, 152, 144, 140, 150, 142, 154.

Find the height of the shortest boy.

Answer 1

Given, height (data) of 15 boys of a class are

128, 144, 146, 143, 136, 142, 138, 129, 140, 152, 144, 140, 150, 142, 154

Arranging the given data in ascending order, we have

128, 129, 136, 138, 140, 140, 142, 142, 143, 144, 144, 146, 150, 152, 154

By observing the data, height of the shortest boy = 128 cm.
