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.

Given:

The given distribution gives the daily income of 50 workers of a factory.

To do:

We have to convert the given distribution to a less than type cumulative frequency distribution and draw its ogive.

Solution:

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

Represent Daily income along X-axis and cumulative frequency along Y-axis.

Plot the points (120, 12), (140, 26), (160, 34), (180, 40) and (200,50) on the graph and join them with a free hand to get the required ogive.
