What Is a Statistical Question?

A statistical question is a question that can be answered using data that may vary. Any question that may be answered by a single number or answer is not considered a statistical question.

An example of a statistical question might be, “how old are the dogs on your street?” This type of data would need to be collected from all the dog owners on the street, and the data may be subject to some variability.

Questions that can be answered with a definitive number are not statistical questions. For example, “how many bricks are in this wall?” is not a statistical question because the number of bricks in the wall can be concisely counted.
