Question

how to find the value of f0 when the modal class appears at the first in the frequency distribution table.....plz guys help me...I really need it​

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-

see the attachment...

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.
