My doubt is--
 
Acttually I haven't understood that when we are constructing a histogram, when do we have to find adjusted frequency or frequency density or are they the same things?

Answer:

Histograms are most commonly used for continuous data.

The vertical axis of histogram is labelled as frequency density, which is calculated by

begin mathsize 16px style F r e q u e n c y space d e n s i t y equals fraction numerator F r e q u e n c y over denominator C l a s s space w i d t h end fraction end style

 

When a histogram with non-uniform (unequal) class widths is to be constructed,

it should be ensured that the areas of the rectangles are proportional to the class frequencies. In this case we need to adjust the frequencies (Adjusted frequency).
