Explanation:
Let’s go through each question step by step, using the bar graph data (even though we can’t see it, the problem implies standard values for the 2002 Winter Olympics medal counts — and from real-world knowledge, the top four countries were: Germany (36), USA (34), Norway (25), Canada (17)). But since this is a math exercise based on reading a graph, we’ll infer values *from the description* in the problem: the y-axis goes from 0 to 40 in increments of 5, and the bars are approximately at:
- Germany: ~36
- USA: ~34
- Norway: ~25
- Canada: ~17
These match actual 2002 Winter Olympics totals and align with typical textbook graphs for this question.
1.
Which country appears to have won approximately half the number of medals won by the United States?
USA ≈ 34 → half of 34 is 17.
Which country has ~17? Canada.
✔ So answer: Canada.
2.
Estimate the number of medals by each country using the left-side numbers (y-axis).
Read bar heights:
- Germany: just above 35 → 36
- USA: just below 35 → 34
- Norway: halfway between 20 and 30 → 25
- Canada: just above 15 → 17
So estimates: Germany = 36, USA = 34, Norway = 25, Canada = 17.
3.
Use estimates from #2 to check if answer to #1 is accurate.
Half of USA’s 34 = 17.
Canada has 17 → exact match.
So yes, the answer in #1 is accurate.
4.
How is the graph misleading?
The y-axis starts at 10, not at 0. This makes differences look bigger than they are. For example, Canada’s bar (17) looks much shorter than USA’s (34), but visually the gap seems huge — when in reality, 17 is about half of 34. Starting at 10 exaggerates relative heights. Also, there’s no clear labeling of exact numbers on bars, so estimation is required — which can cause errors.
5.
How could you modify the graph to represent the data more accurately?
- Start the y-axis at 0 instead of 10.
- Add exact numbers on top of each bar (e.g., “36”, “34”, etc.).
- Use consistent spacing and avoid 3D or decorative effects that distort perception.
Final Answer:
1. Canada
2. Germany: 36, USA: 34, Norway: 25, Canada: 17
3. Yes, because 17 is exactly half of 34
4. The y-axis does not start at 0, making differences appear larger than they are
5. Start the y-axis at 0 and label exact medal counts on each bar
