Statistical vs Non-statistical Questions

Front

What is a statistical question?

Back

A statistical question is one that anticipates variability in the data and can be answered by collecting data. For example, 'How many hours do students spend on homework each week?'

Front

What is a non-statistical question?

Back

A non-statistical question is one that does not anticipate variability in the data and can be answered with a single value. For example, 'What is your favorite color?'

How can you tell if a question is statistical?

A question is statistical if it requires data collection from multiple subjects and expects different answers. For example, 'How many pets do students in your class have?' is statistical.

Front

How can you tell if a question is non-statistical?

Back

A question is non-statistical if it can be answered with a single fact or does not involve variability. For example, 'What is the capital of France?' is non-statistical.
