The heights (in cm) of 50 students of a class are given below:
Height (in cm) | 156 | 154 | 155 | 151 | 157 | 152 | 153 |
Number of students | 8 | 4 | 10 | 6 | 7 | 3 | 12 |
Find the median for the following height.
By arranging the data in ascending order,
Height (in cm) (x) | No. of students (f) | Cumulative frequency |
151 | 6 | 6 |
152 | 3 | 9 |
153 | 12 | 21 |
154 | 4 | 25 |
155 | 10 | 35 |
156 | 8 | 43 |
157 | 7 | 50 |
N = 50 |
We have,
N = 50 (even number)
Median =
As we can see height of 25th student is 154 and 26th student has the height of 155 cm
So the median height is 154.5cm
