Question:
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
Solution:
(i) Arranging the numbers in ascending order:
14, 14, 14, 14, 17, 18, 18, 18, 22, 23, 25, 28
Here the observation 14 is having the highest frequency i. e, 4 in given data, so mode = 14.
(ii) 7, 9, 12, 13, 7, 12, 15, 7, 12, 7, 25, 18, 7
Since maximum frequency 5 corresponds to the value 7 then mode = 7
