Question
Explain briefly the advantages and limitations of graphical presentation of data.
✓

Answer

The following are the advantages of graphical presentation:
  1. Simple Form: It presents the complex data in a simple or understandable form.
  2. Forecasting: It is used for forecasting, interpolation and extrapolation. This helps to assess the future changes in the value of the variable.
  3. Study of Variations: With the help of graphs, we can study the variations in the values of variables and can take corrective actions.
  4. Attractive: Graphical presentation helps to present the data in an attractive manner which makes it interesting and impressive.
  5. Essay Comparison: Graphical presentation of data facilitates easy comparison between the values of the data.
  6. Universal Utility: Graphical presentation is popularly used in journal, news papers, board meeting, etc to give the required information to the general users.
  7. Helpful in Computing Statistical Averages: Statistical averages such as median, quartile, deciles, etc can be easily computed with the help of graphical presentation.
Graphical presentation of data suffers from the following limitations:
  1. 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.
  2. Lead to Wrong Conclusions It may sometimes suggest wrong conclusions and give misleading information.
  3. 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.
