Question

For drawing a frequency polygon of a continuous frequency distribution, we plot the points whose ordinates are the frequencies of the respective classes and abscissae are the:

• A. upper limits of the classes
• B. lower limits of the classes
• C. class marks of the classes
• D. upper limits of perceeding classes

Answer 1

Answer: (C)

class marks of the classes

For drawing a frequency polygon of a continuous frequency distribution,

we draw the class marks of the classes on the abscissae and the frequency of the classes on the ordinates.

We know, class marks are the mean of lower and upper limit of the class intervals.

Hence, option $C$ is correct.
