The following distribution gives the daily income of 50 workers of a factory: Daily income (in Rs.): 100-120 120-140 140-160 160-180 180-200 Number of workers: 12 14 8 6 10 Convert the above distribution to a less than type cumulative frequency distribution and draw its ogive.

Philoid · Accepted Answer

We first prepare cumulative frequency table by less than method as given below:

Daily income (in Rs.)	Cumulative frequency
Less than 120	12
Less than 140	26
Less than 160	34
Less than 180	40
Less than 200	50

Now we mark on x-axis upper class limit and on y-axis cumulative frequency. Thus, we plot the points: (120, 12); (140,26); (160,34); (180,40); (200,50)

Daily income (in Rs.):	100-120	120-140	140-160	160-180	180-200
Number of workers:	12	14	8	6	10
