Provide an appropriate response.Shortly before an election, a market research firm took a poll to find out whether people were planning to vote for or against a particular ballot measure. The results are shown below.
Against3087In favor3691Undecided910The ballot measure will pass if a simple majority (more than 50%) vote in favor of the measure. 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.
What will be an ideal response?
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.
