Items of Expenditure Food Clothing House Rent Fuel and lighting Miscellaneous Total Family A (Income Rs.5000) 2000 1000 800 400 800 5000 Family B (income Rs.8000) 2500 2000 1000 500 2000 8000 Solution: The items of expenditure will be converted into percentage as shown below: 75 Family A Rs. Y 2000 40 1000 20 800 16 400 8 800 16 5000 100 Items of Expenditure Food Clothing House Rent Fuel and Lighting Miscellaneous Total Family B Rs. Y 2500 31 2000 25 1000 13 500 6 2000 25 8000 100 SUBDIVIDED PERCENTAGE RECTANGULAR DIAGRAM 120 Percentage 100 80 60 40 20 0 Family A (0-5000) Food Clothing House Rent Family B (0-8000) Fuel and Lighting Miscellaneous Squares: The rectangular method of diagrammatic presentation is difficult to use where the values of items vary widely. The method of drawing a square diagram is very simple. One has to take the square root of the values of various item that are to be shown in the diagrams and then select a suitable scale to draw the squares. Example 7: Yield of rice in Kgs. per acre of five countries are Country U.S.A Australia U.K Canada Yield of rice in Kgs per 6400 1600 2500 3600 acre Represent the above data by Square diagram. 76 India 4900 Solution: To draw the square diagram we calculate as follows: Country Yield Square root Side of the square in cm U.S.A 6400 80 4 Australia 1600 40 2 U.K. 2500 50 2.5 Canada 3600 60 3 India 4900 70 3.5 4 cm 2cm USA 2.5 cm AUST UK 3 cm CANADA 3.5 cm INDIA Pie Diagram or Circular Diagram: Another way of preparing a two-dimensional diagram is in the form of circles. In such diagrams, both the total and the component parts or sectors can be shown. The area of a circle is proportional to the square of its radius. While making comparisons, pie diagrams should be used on a percentage basis and not on an absolute basis. In constructing a pie diagram the first step is to prepare the data so that various components values can be transposed into corresponding degrees on the circle. The second step is to draw a circle of appropriate size w...
