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.

Explanation

Median class=46-48

l=46

cf=14

f=14

h=2

n=35

Median=`l+(((n/2)+cf)/f)*h`

=`46+(17.5-4)/14*2`
