Text Solution

Verified by Experts

To construct a frequency polygon without first constructing a histogram, one should first mark mid-points of the class intervals on the X-axis. Frequencies are then marked corresponding to the midpoints.
Different points of frequencies are joined to make a frequency polygon.

Based on these data , frequency polygon has been drawn without constructing a histogram, as given below.
