Statistical Question
A question that anticipates variability in answers - it can't be answered with a single number because different data points will give different responses.
"'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?"
Why it matters: Statistics exists because things vary. Recognizing statistical questions is the first step to thinking like a data scientist.
Spread vs Center
Center describes where the 'middle' of data lies; spread describes how far data extends from that center.
"Two pizza delivery services both average 30-minute delivery (same center). But Service A ranges 28-32 minutes, while Service B ranges 10-50 minutes. Same center, wildly different spread. You'd trust A for consistent timing."
Why it matters: A complete picture needs both measures. Just knowing the average isn't enough - you need to know how much things vary.
