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

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

Solution:

The representation of cumulative frequency distribution graphically is known as a cumulative frequency curve or an ogive.

The frequency distribution table of less than type is as follows:

Taking upper-class limits of class intervals on x-axis and their respective frequencies on y-axis, its ogive can be drawn as follows:
