how to a draw frequency polygon with unequal classes without using a histogram??????
Given a frequency distribution of x as
Draw less than and more than ogives on the same graph paper.
Calculate mean value of x variable.
The Indian Sugar Mills Association reported that, ‘Sugar production during the first fortnight of December 2001 was about 3,87,000 tonnes, as against 3,78,000 tonnes during the same fortnight last year (2000). The off-take of sugar from factories during the first fortnight of December 2001 was 2,83,000 tonnes for internal consumption and 41,000 tonnes for exports as against 1,54,000 tonnes for internal consumption and nil for exports during the same fortnight last season.’
