Draw a frequency polygon from the following data by using (i) histogram, and (ii) without using histogram:
Daily Wages (in ₹)
Number of Workers
Using a histogram, a frequency polygon is obtained by joining the top mid-points of the rectangles of the histogram.
When frequency polygon is to be drawn without a histogram then, we simply plot the mid-points of the class intervals with their respective frequencies. The curve obtained on joining the points is the frequency polygon.
