MCQ

In the formula for mode of a grouped data, $\text{ mode} =\text{l}+\left \{\frac {\text{f}_1-\text{f}_0}{2\text{f}_2-\text{f}_0-\text{f}_2}\right \}\times\text{h}$ where symbols have their usual meaning $f_0$ represents:

A
Frequency of modal class
B
Frequency of median class
✓
Frequency of the class preceding the modal class
D
Frequency of the class preceding the Medium class

✓

Answer

Correct option: C.

Frequency of the class preceding the modal class

In the formula for mode of a grouped data,
$\text{ mode} =\text{l}+\left \{\frac {\text{f}_1-\text{f}_0}{2\text{f}_2-\text{f}_0-\text{f}_2}\right \}\times\text{h}$ where symbols have their usual meaning
$f_0$ represents Frequency of the class preceding the modal classwhere
$f =$ Frequency,
$1 =$ 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.
