The question

To answer it, we collect data.
1 Look at who it asks about
It asks about the students.
That is a group: many people or things.
2 See if the answers vary
Each one can give a different answer.
For example: 150 cm, 162 cm, 147 cm, and so on.
The answers vary.
So yes: it is a statistical question.

That is data.
