How many hours did Mary sleep last night?

Question

How many hours did mary sleep last night? is that a Statistical question.

Answer 1

Hi Daisy. No, it is not a statistical question, because there is only one answer and no variability to the data. If you ask "how many hours does she sleep EACH night," that deals with varying data and therefore is statistical.

Answer 2

You can ask Mary, although she may tell you that's none of your business.

 

Or is there some hidden data that you have not shared?
