विकल्प

• upper limits of the classes

• lower limits of the classes

• class marks of the classes

Answer 1

For drawing a frequency polygon of a continous frequency distribution, we plot the points whose ordinates are the frequencies of the respective classes and abcissae are respectively class marks of the classes.

Explanation:

Class marks i.e., the mid-point of the classes are abscissa of the points, which we plot for frequency polygon.
