Vedclass · Answer

(D) In the formula for the mode of a grouped frequency distribution,$f_{1}$ represents the frequency of the modal class,$f_{0}$ represents the frequency of the class preceding the modal class,and $f_{2}$ represents the frequency of the class succeeding the modal class.Given that the modal class is $70-85$ with frequency $25$,we have $f_{1} = 25$.The frequency of the class preceding the modal class is $8$,so $f_{0} = 8$.The frequency of the class succeeding the modal class is $20$,so $f_{2} = 20$.Therefore,the values of $f_{0}, f_{1}$ and $f_{2}$ are $8, 25$ and $20$ respectively.

Class	$0-20$	$20-40$	$40-60$	$60-80$	$80-100$	$100-120$
Frequency	$8$	$9$	$26$	$23$	$20$	$14$

Runs scored	Number of batsmen
$3000-4000$	$4$
$4000-5000$	$18$
$5000-6000$	$9$
$6000-7000$	$7$
$7000-8000$	$6$
$8000-9000$	$3$
$9000-10000$	$1$
$10000-11000$	$1$

In a frequency distribution,the modal class is $70-85$ with frequency $25$. The frequencies of the classes succeeding and preceding the modal class are $20$ and $8$ respectively. Then,the values of $f_{0}, f_{1}$ and $f_{2}$ are respectively.
