Question

describe what is misleading in the following visual display of data.
click the icon to view the bar graph.
choose the correct answer below.
a. the scale of the vertical axis makes the differences in bar height look larger than they really are.
b. the images in front of or behind each bar make it look as though the bars are taller than they really are.
c. the bars are not scaled proportionately in terms of the data they represent.
d. the wrong impression has been created about how the data are changing because equally spaced intervals are not used on the horizontal axis.

Explanation:

When the scale of the vertical axis is not appropriate (e.g., starting from a non - zero value or having an uneven scale), it can exaggerate the differences in bar heights. For example, if the vertical axis starts at a high value instead of zero, the relative differences between the bars will seem larger than they actually are.

Answer:

A. The scale of the vertical axis makes the differences in bar height look larger than they really are.
