9.) Identify all items that are wrong with the graph.
(a) It should be displayed as a pie chart
(b) It has pictures instead of bars
(c) It doesn't accurately represent the data
(the bars aren't the correct height)
(d) There is nothing wrong with the graph
(e) There is no axis that tells us the frequency or
relative frequency.
(f) The axis that tell us frequency or relative
frequency doesn't start at zero.

Because each variable's percentage vary, it's difficult to collect and draw/shape data. However, when analyzing data using a bar graph, the eyes react to the area of the bars as well as their height, giving the correct impression. As the result of the bus and bike/car/automobile ratio, the graph violates the area principle.

(b) The bar graph would be able to depict the genuine distribution of data on the principal mode of school transportation. See the attached image for bar graph for the given data.

Hence,

(a) The graph violates the area principle because of the bus and car ratio.

(b) Here, is the graph that is not misleading.
