Misleading Graphs Paper and Presentation

Graphs are used to give a visual image of data so readers can analyze and translate it quicker and easier than looking at a mass of numbers. However, incorrectly drawn or disproportionately drawn graphs can lead a reader to incorrect translation of data (Bluman, 2009). This document will describe the problems associated with the graph shown below, explain how they affect readers, and what needs to be done to correct the graph (University of Phoenix, 2010).

A bar graph, a pie chart, or even a linear graph would be a better view for the user. Also the source of the data needs to be referenced for the numbers of the singles sold. Below is a representation of the above graph in a standard bar format that does not mislead or misrepresent information (Misleading Graphs, 2011). Looking at the graph below one can clearly tell how many singles were sold for each year.

Conclusion
Graphs and diagrams are useful tools when someone needs to display data in a manner that is compressed and easy to understand. Although this fact is true, one must ensure the clarity and understanding of the diagram remains intact. It is easy to mislead or misinform a spectator if this does not happen. The designer and the reader of the diagrams must pay close attention to the diagram they are viewing or designing. They must be sure to verify the labels on all sides as well as within the diagram. They must first check for clarity of understanding between the key of the diagram and the diagram itself. They must make sure the diagram makes sense overall. Finally, they must ensure that the statistical data being used is represented properly in the diagram being used. These are just some of the things one must deal with when analyzing or designing a diagram or graph.
