The distribution of heights (in cm) of 96

To draw the less than type ogive, we plot 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 point by free hand.

Here, $\frac{N}{2}=\frac{96}{2}$

We take, y = 48 in Y-coordinate and draw a line parallel to X-axis, meets the curve at A and 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.
