  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.  Solution

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. Mathematics
