Question

For a certain frequency distribution, the values of Assumed in $\left(A\right)=1100,\sum f_i{d}_i=800$ and $\sum f_i=100$. Find the value of mean.

Answer 1

Given that $\sum f_i{d}_i=800$ and $\sum f_i=100$

Now we have to find the value of mean , Let it be $x$

We have $x=\frac{\sum f_i{d}_i}{\sum f_i}=\frac{800}{100}=8$

So the value of mean is $8$
