Question

4.
The heights (in cm) of 9 students of a class are as follows !
155, 161, 145, 149, 150, 145, 152, 145, 140.
Find the mean, median and mode of this data​

Answer 1

Answer:

By arranging the numbers in ascending order We get 144, 145, 147, 148, 149, 150, 152, 155, 160 We know that n = 9 which is odd So we get Median = [(n + 1)/2]th value By substituting the values Median = [(9 + 1)/2]th value We get Median = 5th value = 149cm Therefore, the median height is 149cm
