Question

For the following data, draw a 'less than' ogive and hence find the median of the distribution. Age(in yrs. ) 0-10, 10-20, 20-30, 30-40, 40-50, 50-60, 60-70
No. Of persons 5,15,20,25,15,11,9

Answer 1

34

Step-by-step explanation:

Use following table

Here we, have N = 100

so, N/2 = 100/2 = 50

The cumulative frequency just greater than 50 is 65. then 30-40n is the median class such that  h = 10, L=30, f = 25, F = 40.

$\begin{aligned}&\text {Median}=L+\frac{\frac{N}{2}-F}{f} \times h\\&=30+\frac{50-40}{25} \times 10\\&=30+\frac{100}{25}\\&=30+4\\&34\end{aligned}$
