What counts as data
You ask 5 friends how they get to school. Three say bus. Does the whole class come by bus?

The rule
No. Five friends can differ from the whole class.
Data is a fact you collect. You ask, count or measure. Nobody invents the numbers.
To know the whole class, ask the whole class.
Step 1 of 4
- Ask 5 friends.
- 3 of the 5 say bus.
- Ask the whole class: 30 students.
- Only 9 of 30 say bus. That is a much smaller share.
Example
Ask 5 friends. 3 say bus, so bus is the most common answer.
Ask the class of 30. 13 say walk. That is more than 9 for bus.
