The distribution of heights (in cm) of 96 children is given below

Draw a less type cumulative frequencies curve fo this data and use it to compute meidan height of the children.

Explanation

To draw the less than type ogive, we get the points (124,0),(128,5),(132,13),(136,30),(140,54),(144,70),(148,82),(152,88),(156,92),(160,95),(164,96) and join all these points by free hand

Here, `(N)/(2)=(96)/(2)=48`
We take, y=48 in y-cordination and draw a line parallel to X-axis meets the curve at A a draw a perpendicular line from point A to the X-axis and this line meets the X-axis at the point which is the median i.e. median=141.17
