Find the mean, me

Answer :

Mean= =

We have, N= 25,

N/2 = 12.5

Hence, median class =150-200, such that

l=150, f’=6, f=10, h=50

Median = l +

Here, we may observe that maximum class frequency is 6 belonging to the class interval 150-200

So, modal class= 150-200

Lower limit, l= 150

f0=5, f2=5, f=6, h = 50
