a scatterplot a pie chart a bar graph a line graph
I gave my students this multiple choice question: For half an hour, a student watches two different types of flowering bushes and counts the number of butterflies that come to feed on each bush. What would be the best way to show the data?

Only one answer is correct among these 4 choices:
- a scatterplot
- a pie chart
- a bar graph
- a line graph

Could you tell me which one is correct?
