Question

For a certain frequency distribution, the values of Assumed mean (A) = 1300, `sumf_id_i` = 900 and `sumfi` = 100. Find the value of mean (`barx`) .

 

Answer 1

We have 

(A) = 1300, `sumf_id_i` = 900 and `sumfi` = 100=N.

`barx=A+1/Nsum_(i=1)^nf_id_i`

`barx=1300+1/100 xx900`

`barx=1300+9`

`barx=1309`
