To draw a frequency polygon, we have to first draw a histogram.
Answer: Option A
:
A
We don't need to draw a histogram in order to draw a frequency polygon. We can obtain the class mark corresponding to each class interval, which corresponds to the midpoint of the class interval along the x-axis and the corresponding frequency along the y-axis.The lines joining these points will constitute the frequency polygon.
