Statistical Question
Grade 3-5
A question that anticipates variability in answers - it can't be answered with a single number because different data points will give different responses. Statistics exists because things vary.
Definition
A question that anticipates variability in answers - it can't be answered with a single number because different data points will give different responses.
💡 Intuition
'How old is my teacher?' has ONE answer - not statistical. 'How old are teachers at my school?' will have DIFFERENT answers for each teacher - that's statistical! The key: do you expect variation?
🎯 Core Idea
A statistical question expects a range of different answers — it anticipates variability. A non-statistical question has exactly one fixed answer.
