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 | 9 | |
164 | 3 | |
165 | 3 | |
168 | 1 |
Clearly, 163 occurs 9 times. Therefore, is the mode of the data.
