Museum management. Refer to the Museum Management and Curatorship (June 2010) study of how museums evaluate their performance, Exercise 2.14 (p. 74). Recall that managers of 30 contemporary art museums identified the performance measure used most often. A summary of the results is reproduced in the table. Consider the bar graph shown. Identify two ways the bar graph might mislead the viewer by overemphasizing the importance of one of the performance measures.

A misleading graph also referred to as a skewed chart, misrepresents data, resulting in a statistical error and the drawing of an inaccurate conclusion. Graphs can be deceptive if they are overly complicated or badly structured. Even when designed to depict the features of its information accurately, graphs might be vulnerable to conflicting interpretations, and undesired types of information can be created. Deceptive graphs can be intentionally misleading, or they might result in somebody not comprehending the facts underlying the graph they make.

The vertical axis of a bar graph should begin at 0. However, it begins at 12 in this case.

Moreover, because the width is unequal, we cannot comprehend the meaning of area, i.e., final tally.
