3. Which of these can NOT be concluded from the sports bar graph?
- AMore than 30 students voted
- BBadminton beat football
- CEvery student plays cricket at home
- DKabaddi got the fewest votes
Show answer
Answer: C) Every student plays cricket at home
The graph shows only favourite sports. It says nothing about who plays cricket at home. The other three can be read from the bars (6 is the least, 10 > 8, total 38).

5. A bar graph of four shops' sales starts its vertical axis at 40 instead of 0. Why can this mislead a reader?
- AThe order of shops changes
- BSmall differences look very big
- CThe bars become wider
- DThe totals change
Show answer
Answer: B) Small differences look very big
If the axis starts at 40, a shop with 42 sales gets a tiny bar and one with 50 gets a bar five times as tall, even though 50 is not five times 42. Starting at 0 keeps bar heights fair.
