Question

The heights in cm of 9 students of a class are 148 144 152 155 160 147 150 149 145 Find the median height

Accepted 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.
