The following distribution gives daily income of 50 workers of a factory:
Daily income (in Rs):200-220220-240240-260260-280280-300
Number of workers:12148610
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.
