Question

If class sizes are different in a given frequency distribution then to draw the histogram it is required to

• A. Find the cumulative frequency.
• B. Find the mid value and cumulative frequency.
• C. Find the adjusted frequency and cumulative frequency.
• D. Find only adjusted frequency.

Answer 1

The correct option is D Find only adjusted frequency.

While class sizes are different, then to make the comparison properly and to have an unique presentation of data, it is required to get adjusted frequency. It may happen that class with bigger class size having the maximum frequencies while the class with lowest class size have minimum frequency. Those two will not be comparable in a graph. So, it is required to get adjusted frequency.
