A group of students were asked, “Which way do you feel about the new school year?” Their responses are shown in this bar graph:
How many more students are excited about the new school year than are nervous or curious?

- How many more pine trees did Clare see than oak or maple trees?
- How many fewer oak trees did Clare see than pine trees?
- How many fewer maple or oak trees did Clare see than fir trees?
Student Section Summary
We created scaled picture graphs and scaled bar graphs.
The key tells what each picture represents in a picture graph.
The scale tells what number each bar represents in a bar graph.
We asked and answered questions about data represented in the graphs.
- How many more daisies were seen than violets?
- How many fewer students walk home than bike home?
- How many more students bike home than walk or ride in a car?
