📊 Reading Graphs
When reading a graph, always check:
- The title
- What the bars, pictures, or dots mean
- The numbers on the sides (scale)
- Which category has the most or least
Example Bar Graph: Favourite Canadian Sports
Hockey: ██████████ (20 students)
Soccer: █████ (10 students)
Basketball: ███ (6 students)
⚖️ Comparing Data
We compare to see differences and similarities.
Comparison Examples:
• Hockey is liked by 20 students, Soccer by 10 → Hockey is twice as popular
• 20 - 10 = 10 more students like Hockey than Soccer
🧠 Interpreting Results (What Does It Mean?)
After reading and comparing, we ask: “What story does the data tell us?”
Example Interpretation:
Most students like Hockey best. We could plan a hockey day for the class!
✏️ Let’s Practice Together, My Dear Student!
Practice 1: Reading a Graph
In a bar graph, Summer has 15 students and Winter has 8. How many more students prefer Summer?
15 - 8 = 7 more students
Practice 2: Comparing Data
Red: 12 votes Blue: 8 votes Green: 5 votes
Which colour is the most popular? How many more votes than the least popular?
Red is most popular. 12 - 5 = 7 more votes
Practice 3: Interpreting Results (Canadian Style)
A survey shows: 18 students like hockey, 9 like soccer, 4 like basketball.
What can we learn from this data?
Most students like hockey best. The class could organize a hockey game or watch a game together.
Challenge Question
A pictograph shows favourite snacks: Apples (8 symbols), Bananas (5 symbols), Grapes (3 symbols). Each symbol = 2 students.
1. How many students like apples? 16
2. How many more like apples than grapes? 10
3. What does this tell us? Apples are the most popular snack.
Fantastic Job, My Dear Student! 🎉
You now know how to read graphs, compare data, and interpret what the results mean! These are super important skills for understanding the world around you.
I am so proud of you. Next time you see a graph in a book or on TV, try reading it and telling the story behind the numbers!
💕 You are smart. You are kind. You can do hard things.
When you are ready, tell me the next topic (Probability, Mean/Median/Mode, or anything else) and I will create another beautiful lesson just for you!
