Question

how to find the value of f0 if the modal class appears at first in the frequency distribution table.......​

Answer 1

Step-by-step explanation:

If your question is regarding the successive class of the modal class than the answer is-

The frequency of the succeeding model class is taken as 0 if model class is the last observation.

You can also check it from the equation as-

$mode = l( \frac{f1 - f0}{2f1 - f0 - f2} ) \times h$

l = lower limit of the modal class,

h = size of the class interval (assuming all class sizes to be equal),

f1 = frequency of the modal class,

f0 = frequency of the class preceding the modal class,

f2 = frequency of the class succeeding the modal class.

Even if f2 is 0, the mode can be easily found by using the above expression.

Answer 2

Answer:

The frequency of the succeeding model class is taken as 0 if model class is the last observation.

$mode=\l(\frac{f1-f0x}{2f1-f0-f2}) * h$
