Worksheet with a bar graph displaying student preferences for subjects, including questions about scale, popularity, and equal numbers.

Let’s go step by step to answer each question using the bar graph.

First, look at the vertical axis (left side) — it says “Number of Students” and goes from 0 to 60 in steps of 5. So each line on the grid represents 5 students. That’s our scale.

Now let’s read the height of each bar:

- Social Studies: The bar reaches 30 → 30 students
- Math: The bar reaches 50 → 50 students
- Science: The bar reaches 30 → 30 students
- ELA: The bar reaches 35 → 35 students
- Others: The bar reaches 10 → 10 students

Now answer each question:

1. What unit of scale is used?
→ Each line on the y-axis increases by 5. So the unit of scale is 5.

2. Which subject is the second most popular?
→ Most popular is Math (50). Next highest is ELA (35). So ELA is second most popular.

3. Which subject is less popular, science or ELA?
→ Science = 30, ELA = 35 → So Science is less popular.

4. Which subject is the favorite of 50 students?
→ Look for the bar that reaches 50 → That’s Math.

5. Which subjects have the same number of votes?
→ Social Studies = 30, Science = 30 → So Social Studies and Science have the same number.

Double-checking all answers against the graph values:
- Scale: yes, increments of 5 ✔️
- Second most popular: Math (50), then ELA (35) ✔️
- Less popular between Science (30) and ELA (35): Science ✔️
- Favorite of 50: Math ✔️
- Same votes: Social Studies and Science both 30 ✔️

Final Answer:
1. 5
2. ELA
3. Science
4. Math
5. Social Studies and Science
