Find the mode of the following data in each case:
(i) 14, 25, 14, 28, 18, 17, 18, 14, 23, 22, 14, 18
(ii) 7, 9, 12, 13, 7, 12, 15, 7, 12, 7, 25, 18, 7
(i) Arranging the data in ascending order:
14, 14, 14, 14, 17, 18, 18, 18, 22, 23, 25, 28
Here observation 14 is having the highest frequency.
So, mode = 14
(ii)
Values | 7 | 9 | 12 | 13 | 15 | 18 | 25 |
Frequency | 5 | 1 | 3 | 1 | 1 | 1 | 1 |
Since, maximum frequency 5 corresponds to value 7.
Then, the mode = 7
