Rules for Constructing Diagrams

While constructing diagrams for statistical data, the following guidelines are to be kept in mind:

·           A diagram should be neatly drawn in an attractive manner

·           Every diagram must have a precise and suitable heading

·           Appropriate scale has to be defined to present the diagram as per the size of the paper

·           The scale should be mentioned in the diagram

·           Mention the values of the independent variable along the X-axis and the values of the dependent variable along the Y-axis

·           False base line(s) may be used in X-axis and Y-axis, if required

·           Legends should be given for X-axis, Y-axis and each category of the independent variable to show the difference

·           Foot notes can be given at the bottom of the diagram, if necessary
