Unformatted text preview: ponents are not the actual values but percentages of the whole. The main difference between the sub-divided bar diagram and percentage bar diagram is that in the former the bars are of different heights since their totals may be different whereas in the latter the bars are of equal height since each bar represents 100 percent. In the case of data having sub-division, percentage bar diagram will be more appealing than sub-divided bar diagram. 73 Example 5: Represent the following data by a percentage bar diagram. Particular Selling Price Quantity Sold Wages Materials Miscellaneous Factory A 400 240 3500 2100 1400 Factory B 650 365 5000 3500 2100 Solution: Convert the given values into percentages as follows: Factory A Rs. % 400 5 240 3 3500 46 2100 28 1400 18 7640 100 Particulars Selling Price Quantity Sold Wages Materials Miscellaneous Total Solution: Factory B Rs. % 650 6 365 3 5000 43 3500 30 2100 18 11615 100 Sub-divided PercentageBar Diagram Percentages 100 80 60 40 20 0 Factory A Factory B Particulars Selling price Quantity sold Materials Miscellaneous 74 5.5.2 Two-dimensional Diagrams: In one-dimensional diagrams, only length 9 is taken into account. But in two-dimensional diagrams the area represent the data and so the length and breadth have both to be taken into account. Such diagrams are also called area diagrams or surface diagrams. The important types of area diagrams are: 1. Rectangles 2. Squares 3. Pie-diagrams Rectangles: Rectangles are used to represent the relative magnitude of two or more values. The area of the rectangles are kept in proportion to the values. Rectangles are placed side by side for comparison. When two sets of figures are to be represented by rectangles, either of the two methods may be adopted. We may represent the figures as they are given or may convert them to percentages and then subdivide the length into various components. Thus the percentage sub-divided rectangular diagram is more popular than sub-divided rectangular since it enables comparison to be made on a percentage basis. Example 6: Represent the fol...
