During the medical check-up of 35 students of a class, their weights were recorded as follows :

Draw a less than type ogive for the given data. Hence obtain the median weight from the graph and verify the result by using the formula.

Answer

Draw the ogive by plotting the points : (38, 0), (40, 3), (42, 5), (44, 9), (46, 14), (48, 28), (50, 32) and (52, 35). Here `(n)/(2) = 17.5` n =17.5. Locate the point on the ogive whose ordinate is 17.5. The x-coordinate of this point will be the median.
