Following are the limitations of diagrammatic presentation Graphical presentation is an important and effective means of displaying statistical data, but it should be used keeping in view its limitations.
It has the following limitations :
- Useful in comparative study : Diagrammatic presentation can be used only if it is to create diagrams with at least two identical qualities. There is no meaning in making a single diagram. Diagrammatic presentation is useful only in the comparative study.
- Equal property and nature required : When all the diagrams are created on the basis of similar qualities, then they can be compared. If the diagrams are made based on different qualities, they will give misleading conclusions.
- Approximate Presentation : Diagrams are based on approximate value. For this reason, they cannot present the reality of facts. They can only give an estimated presentation of data.
- Difficult to display subtle and vast differences : It is not possible to display a subtle difference of different values through diagrams. Similarly, it is not possible to display the numbers with large difference.
- The presentation of versatile properties is impossible : Through classification and tabulation, we can display multi property information, but it is not possible to do this by diagram. Through diagrams, it is possible to display only three or four properties.
- Numerical Presentation Impossible : Numerical presentation is not possible through diagrams. Absolute quantitative accuracy cannot be expected from them.
- Misuse : It is often misused by selfish people to fulfill their objectives.
- Analysis is not feasible in the future : If a topic is displayed by diagrams, then considering the situation in the future, it is not possible to analyze the old diagram.
