Question

Choose the correct statement(s) given in the options for frequency polygon.

• A. Frequency polygon is graphical representation of discrete frequency distribution.
• B. Frequency polygon is graphical representation of continuous frequency distribution.
• C. Construction of histogram is required for building the frequency polygon.
  
• D. There is no need of class marks in constructing the frequency polygon.

Answer 1

Answer: (A), (B)

The correct options are
A Frequency polygon is graphical representation of discrete frequency distribution.
B Frequency polygon is graphical representation of continuous frequency distribution.

A frequency polygon is the graphical representation of both discrete and continuous frequency distribution.

But class marks are first calculated, then they are taken on the X-axis and the corresponding frequency on the Y-axis in constructing the frequency polygon.

Alwyas there is no need for constructing the histogram, the frequency polygon can be made without using the histogram.
