- 4. LEARNING OUTCOMES • Students will be able to analyze and interpret with in the Contexts they are written in Diagrams and to present data Graphically using Histogram, Frequency Polygon and Curve, and Pie charts
- 5. SESSION - 22 • Two Dimensional Bar Diagram (Squares, Pie Diagram and Rectangle Bar Diagram) Problem-02
- 6. Two Dimensional Bar Diagrams • SQUARES The method of drawing a square diagram is very simple. One has to take the square root of the values of various items that are to be shown in the diagrams and then select a suitable scale to draw the squares.
- 7. CONTD QUESTION 01 Construct a Suitable Bar Diagram. From the below following information YEAR EXPORT 1 100 2 150 3 300 4 450 5 500 6 575 7 600
- 9. CONTD • Rectangle Bar Diagram It is a two dimensional bar diagram. Because, length and width of the bar is considered for the purpose of representing the data. A comparative study can be best conducted by means of rectangles side by side.

- 13. CONTD • Pie Diagram Another two dimensional diagram or circular diagram is the Pie diagram. As the diagram looks like a pie, it is given this name. A circle which has 360c is divided into different sectors. Angles of the sectors, subtending at the center, are proportional to the magnitudes of the frequency of the components Component value Degree of component = X 360 Total value
