First form the frequency distribution table with the given data.
 
Now check the class width of the distribution.
 
If the class width is not uniform (not a constant), then we need to draw a histogram of varying width.
 
Now choose the smallest width as the standard width.
 
Therefore, the other widths are the multiples of the standard width.
 
Adjust the heights of the rectangles accordingly.
