Bar graph worksheet for students to practice interpreting data from visual representations.

Let’s solve each question step by step using the bar graphs.

First Graph: Preferred Drink

The y-axis shows “Number of People” from 0 to 10.
The x-axis lists drinks: Juice, Soda, Milk, Water, Lemonade.

Look at the height of each bar:

- Juice → bar reaches 3 → 3 people
- Soda → bar reaches 7 → 7 people
- Milk → bar reaches 2 → 2 people
- Water → bar reaches 9 → 9 people
- Lemonade → bar reaches 4 → 4 people

Now answer the questions:

1) How many people prefer to drink water?
→ Look at the “Water” bar → it goes up to 9.
✔ Answer: 9

2) How many people were surveyed in total?
→ Add all the numbers:
3 (Juice) + 7 (Soda) + 2 (Milk) + 9 (Water) + 4 (Lemonade) =
3 + 7 = 10
10 + 2 = 12
12 + 9 = 21
21 + 4 = 25
✔ Answer: 25

3) How many more people prefer soda over milk?
→ Soda = 7, Milk = 2
→ 7 - 2 = 5
✔ Answer: 5

4) Would it be logical for this bar graph to have a value that goes in between the y-axis values? Why or why not?
→ The y-axis counts *people*. You can’t have half a person. So no — you can’t have values like 3.5 or 6.7 because people are whole numbers.
✔ Answer: No, because you can’t have part of a person — only whole numbers make sense.

Second Graph: Baking Time

Y-axis = Minutes (from 0 to 50)
X-axis = Items: Muffin, Cookie, Cake, Brownie, Bread

Bar heights:

- Muffin → 30 minutes
- Cookie → 15 minutes
- Cake → 45 minutes
- Brownie → 25 minutes
- Bread → 48 minutes (just under 50)

5) How many minutes does it take to bake bread?
→ Bread bar is just below 50 → looks like 48 minutes
✔ Answer: 48

6) If I want to bake both cookies and muffins how many minutes will the oven be on?
→ Cookie = 15 min, Muffin = 30 min
→ But wait — do we add them? Only if baked one after another. The question says “both”, so assume sequential baking.
→ 15 + 30 = 45 minutes
✔ Answer: 45

7) About how long does it take to bake a brownie?
→ Brownie bar is halfway between 20 and 30 → 25 minutes
✔ Answer: 25

8) What’s the difference in bake time between bread and cake?
→ Bread = 48 min, Cake = 45 min
→ 48 - 45 = 3 minutes
✔ Answer: 3

Final Answer:

1) 9
2) 25
3) 5
4) No, because you can't have part of a person — only whole numbers make sense.
5) 48
6) 45
7) 25
8) 3
