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	$0-10$	$10-20$	$20-30$	$30-40$	$40-50$	$50-60$	$60-70$	$70-80$
Frequency	$6$	$8$	$17$	$x$	$42$	$30$	$y$	$8$

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.
