What is a statistical question?

A statistical question is a question that can be answered by collecting and analyzing data, and for which there is variability in the data. It differs from a question with a single, definitive answer. The core concept is that you expect to see a range of different data points.

Key aspects of a statistical question include:

• Data Collection: It requires the collection of some form of data to answer it. For more information, you can check out the page about Data%20Collection.
• Variability: The collected data is expected to exhibit variation. You will not get the same answer every time. Understand more about Variability.
• Analysis: The data collected must be analyzed, often using statistical methods, to draw conclusions. Learn more about Statistical%20Analysis.

Examples of statistical questions:

• "What is the average height of students in this school?"
• "How many hours of sleep do people in this city get on average per night?"
• "What is the most popular color of cars in this parking lot?"

In contrast, non-statistical questions have a single, easily determinable answer, such as "What is my age?".
