Brenda is the owner of Brenda’s Hair Salon. She produced the following graph to show that her customers are more satisfied than customers of two nearby salons owned by Nancy and Tammy. Which statement best describes why the graph is misleading?
A horizontal bar graph titled 'Salon Satisfaction Rating' is shown.
Three bars of data are represented on the graph. The horizontal axis shows a short distance to 85 percent from the left, a longer distance to 90 percent, an equal distance to 95 percent, and another equal distance to the unlabeled end of the axis.
· The first bar is labeled 'Nancy's' and extends horizontally to less than half way between 90 percent and 95 percent.
· The second bar is labeled 'Tammy's' and extends horizontally to more than halfway between 90 percent and 95 percent.
· The third bar is labeled 'Brenda's' and extends horizontally to more than halfway between 95 percent and the end of the graph.
A. It is difficult to determine the actual satisfaction levels for each salon, so a clear comparison cannot be made.
B. Brenda’s ratings look better than they really are because the graph does not start at zero.
C. Using percentages makes it seem like there is a large difference in customer satisfaction between Brenda’s Hair Salon and its competitors.
D. Not enough salons were included in the survey.
