(Q2) The following distribution gives the daily income of 50 workers of a factory.

Daily Income (in Rupees) 250-300 300-350 350-400 400-450 450-500
Number of workers 12 14 8 6 10

Convert the distribution above to a less than type cumulative frequency distribution, and draw its ogive.

Answer:

Since the curve is a less than type graph the data changes to

Class Interval f c.f Points
Less than 300 12 (300, )
Less than 350 14 (350,)
Less than 400 8 (400, )
Less than 450 6 (450, )
Less than 500 10 (500, )

X-axis-upper limits 1 cm = 50 units.

Y-axis-less than c.f. 1 cm = 5 units.
