Solution
△ Identify issues with the given graphic.
○ Analyze option A
▷ Evaluate if the graphic's endpoint is unclear.
☼ Option A suggests a pictograph issue, but without the graphic, confirmation is difficult.
○ Analyze option B
▷ Assess clarity of the "Don't Know" category.
☼ Option B indicates a labeling issue, but the category is clearly labeled in the provided graphics.
○ Analyze option C
▷ Evaluate category size representation.
☼ Option C highlights unequal category sizes, a valid concern for data misrepresentation.
○ Analyze option D
▷ Consider appropriateness of graphic type.
☼ Option D suggests inappropriate graphic types for categorical data, making it likely incorrect.
✧ The problem with the graphic is that the categories are not the same size, which misrepresents the data (Option C).
△ Choose a non-misleading graphic for the data.
○ Evaluate bar chart options
▷ Compare bar chart representations.
☼ Both bar charts (A and B) correctly represent percentages but may mislead due to equal bar widths.
○ Evaluate pie chart option
▷ Assess pie chart suitability.
☼ The pie chart (C) effectively shows proportions without implying equal intervals, avoiding misrepresentation.
○ Evaluate dot plot option
▷ Consider dot plot effectiveness.
☼ The dot plot (D) lists percentages but lacks visual representation of proportions.
✧ The correct graphic that is not misleading and makes the data stand out is the pie chart (C).
☺The correct answer is C.
