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.

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.
