You wish to construct a graph to represent the data. It should be easy to see from your graph whether more than 50% of the people are planning to vote in favor of the measure. Which graph would be more useful, a bar graph or a pie chart? Explain your thinking.

Question

What will be an ideal response?

Answer 1

Answers will vary. Possible answer: A pie chart would be more useful. A pie chart is useful for comparing the size of each category with the whole (ie the proportion of the whole population falling in each category). A bar graph is more useful for comparing the sizes of different categories with each other.
