Question

the following bar graph shows the median income for females in a certain region from 2018 to 2022. complete parts (a) and (b). click the icon to view the bar graph of female income. (a) how is the bar graph misleading? what does the graph seem to convey? a. the horizontal axis starts at 2018 instead of 0. this makes the time period look shorter than it really is. b. the vertical axis starts at 35,000 instead of 0. this tends to indicate that the median income for females changed at a faster rate than it actually did. c. the vertical axis starts at 35,000 instead of 0. this makes where the bars should start unclear. the vertical scaling is incorrect. all the bars look larger than they should. d. the taller bars have greater widths. the taller bars have a much greater area than the shorter bars.

Explanation:

To determine how the bar graph is misleading, we analyze each option:

• Option A: The horizontal axis (time) starting at 2018 instead of 0 doesn't mislead about income change rate, so A is incorrect.
• Option B: If the vertical axis (income) starts at 35,000 instead of 0, the differences between the bars (representing income over years) appear more dramatic. This exaggerates the rate of change in median income, which matches how misleading bar graphs with non - zero vertical axis starts work.
• Option C: Saying the vertical axis start makes bar start unclear is not the main issue. The key is the misrepresentation of the rate of change, not unclear bar starts or incorrect scaling in the way described, so C is incorrect.
• Option D: The problem is about the vertical axis start, not bar widths. So D is incorrect.

Answer:

B. The vertical axis starts at 35,000 instead of 0. This tends to indicate that the median income for females changed at a faster rate than it actually did.
