Question

In the formula for mode of a grouped data, mode $=l+\left\{\frac{f_1-f_0}{2f_2-f_0-f_2}\right\}\times h$, where symbols have their usual meaning $f_0$ represents

• A. Frequency of modal class
• B. Frequency of median class
• C. Frequency of the class preceding the modal class
• D. Frequency of the class succeeding the modal class

Answer 1

The correct option is C Frequency of the class preceding the modal class

In the formula for mode of a grouped data, mode $=l+\left\{\frac{f_1-f_0}{2f_2-f_0-f_2}\right\}\times h$, where symbols have their usual meaning $f_0$ represents Frequency of the class preceding the modal class

where $f=$ Frequency, $l=$ Lowest value of the modal range, $f_1=$ Frequency of modal class,

$f_2=$ Frequency of class succeeding the modal class and $f_0=$ Frequency of class preceding the modal class.

Hence, option C is correct.
