Null questions are questions in which one factor is not believed to have any association with what is mentioned in comparison to it. Examples of null questions include:
Do dogs care about the color of their chow?
This is a null question because animals generally don’t express a personal preference or dislike based on the color of their food.
Do children use more internet access than adults?
This is a null question because age doesn’t have a direct effect on the internet access of children or adults.
