Therefore, the median class in (150 - 160)
l = 150, c.f = 151, h = 10, f = 116
Therefore,
= 150 + 3.79 = 153.79.
Example-8: The following table gives the frequency distribution of married
women by age at marriage.

Obtain the median.
Solution:-Transforming the given series into an exclusive one, we get the following
table.
