Steps of Construction:

(i) We represent the daily income on the horizontal axis. We choose the scale on horizontal axis as 1 cm = Rs. 1000.

(ii) We represent the number of doctors (frequency) on the vertical axis. Since the maximum frequency is 12, we choose the scale as 1 cm = 2 doctors.

(iii) We now draw rectangles (or rectangular bars) of width equal to the class-size and lengths according to the frequencies of the corresponding class intervals.
