✓
Answer
The following are the advantages of graphical presentation:
- Simple Form: It presents the complex data in a simple or understandable form.
- Forecasting: It is used for forecasting, interpolation and extrapolation. This helps to assess the future changes in the value of the variable.
- Study of Variations: With the help of graphs, we can study the variations in the values of variables and can take corrective actions.
- Attractive: Graphical presentation helps to present the data in an attractive manner which makes it interesting and impressive.
- Essay Comparison: Graphical presentation of data facilitates easy comparison between the values of the data.
- Universal Utility: Graphical presentation is popularly used in journal, news papers, board meeting, etc to give the required information to the general users.
- Helpful in Computing Statistical Averages: Statistical averages such as median, quartile, deciles, etc can be easily computed with the help of graphical presentation.
- Actual/ Precise Values are not Disclosed Graphical presentation merely shows the tendency and fluctuations. Actual and precise values are not disclosed through a graphical presentation, so it does not show precise values.
- Lead to Wrong Conclusions It may sometimes suggest wrong conclusions and give misleading information.
- Limited Information Graphical presentation can be used to depict only one or two characteristics. Because of this, only limited information can be presented through this presentation.
