# 2. Heights (in cm) of 25 children are given below: 168, 165, 163, 160, 163, 161, 162, 164, 163, 162, 164, 163, 160, 163, 160, 165, 163, 162, 163, 164, 163, 160, 165, 163, 162 What is the mode of their heights? What do we understand by mode here?

 Heights Tally bars Number 160 $||||$ 4 161 $|$ 1 162 $||||$ 4 163 $\cancel{||||}||||$ 9 164 $|||$ 3 165 $|||$ 3 168 $|$ 1
Clearly, 163 occurs 9 times. Therefore, $163\ cm$  is the mode of the data.
