green: 3yellow: 5orange: 2 Red (7), blue (9), and purple (8) were each chosen by more than 5 students. Green (3), yellow (5), and orange (2) were each chosen by 5 or fewer students.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. The most popular color is blue.
Blue was chosen by 9 students, which is more than any other color.
2. How many more chose blue than green? 6.
Blue had 9 votes and green had 3 votes. 9 − 3 = 6 more students chose blue.
3. A bar graph uses bars to show data.
A bar graph uses rectangular bars of different heights or lengths to display and compare data.
4. The total number of students surveyed is 34.
Add all the votes: 7 + 9 + 8 + 3 + 5 + 2 = 34 students voted in total.
5. A graph key tells us what each picture or bar represents.
In a picture graph, each picture or symbol can represent one or more items, as shown by the key.
Part C: True or False?
Read each statement. Circle True or False.
1. Purple was chosen by more students than red.
True False
Every graph should have a title that tells the reader what data is being shown.
