Question

consumers ratings for a fab lawnmower range from one star (strongly dislike) to five stars (strongly like). the results are shown in the bar graph below. consumer ratings for fab lawnmower (vertical axis 70–80, bars for 1–5 stars). identify any misrepresentation issues in the graph. select all that apply. select all that apply: there are distracting visual effects in that different colorings are used for the bars. the vertical axis scale is not appropriate. the horizontal axis ticks are not placed correctly. the horizontal axis scale is not appropriate.

Explanation:

1. Vertical axis scale: The vertical axis starts at 70 instead of 0, which can exaggerate differences between bar heights. This is a common misrepresentation in bar graphs as it distorts the visual comparison of the data (e.g., the 5 - star bar looks much taller relative to others than it would if the axis started at 0).
2. Distracting visual effects (color): Using different colors for bars can be distracting and may imply (incorrectly) that different categories (star ratings) are of different types or importance, which is a misrepresentation as all are consumer ratings.
3. Horizontal axis ticks: The 3 - star category has no bar, but the tick is present. Also, the spacing or placement of ticks (e.g., 1, 2, 3, 4, 5 stars) should have corresponding bars, and the absence of a bar for 3 stars with a tick there is incorrect. The horizontal axis scale (categories: 1 - 5 stars) is appropriate as it's the range of ratings, so that option is incorrect.

Answer:

• The vertical axis scale is not appropriate.
• There are distracting visual effects in that different colorings are used for the bars.
• The horizontal axis ticks are not placed correctly.
