What is a statistical question?
A statistical question is one that can be answered by collecting data and expects variability in the answers.
Give an example of a question that is not statistical.
"What is my age?" is not a statistical question because it has only one specific answer and no variability.
Why is "How many pets do students have?" a statistical question?
Because different students may have different numbers of pets, so the answers will vary. This variability is what makes the question statistical.
