Vedclass · Answer

(C) The formula for calculating the $k^{th}$ decile $(D_k)$ in a continuous frequency distribution is given by: $D_k = l + \frac{(\frac{kN}{10} - C)}{f} 	imes i$ where: $l$ is the lower limit of the decile class,$N$ is the total frequency,$C$ is the cumulative frequency of the class preceding the decile class,$f$ is the frequency of the decile class,$i$ is the class interval size. For the $7^{th}$ decile $(k=7)$,the formula becomes: $D_7 = l + \frac{(\frac{7N}{10} - C)}{f} 	imes i$. Therefore,the correct option is $C$.

Class	$0-20$	$20-40$	$40-60$	$60-80$	$80-100$
$f$	$17$	$f_1$	$32$	$f_2$	$19$

For a frequency distribution,the $7^{th}$ decile is computed by the formula:
