5.1.2 Comparison of Tabular and Diagrammatic Presentation

 Data may be presented in the form of tables as well as diagrams and graphs. Both forms of presentation have their own usefulness for particular purposes. Hence, the choice of the form of presentation must be made with due thought and care. The following points may be kept in view in this connection :

1. Tables contain precise figures whereas diagrams give only an approximate idea. Exact values can be read from a table.

2. More information can be presented in one table than either in one graph or diagram.

3. Tables usually require much close reading and are more difficult to interpret than diagrams.

4. Graphs and diagrams have a visual appeal and, therefore, prove to be more impressive to laymen.
