The following distribution gives daily income of 50 workers of a factory:

Daily income (in Rs):	200-220	220-240	240-260	260-280	280-300
Number of workers:	12	14	8	6	10

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

Given:

The given distribution gives 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 (220, 12), (240, 26), (260, 34), (280, 40) and (300,50) on the graph and join them with a free hand to get the required ogive.
