    Definition by Guilhem, Nathan and Julie

    A good statistical question is a question that can be answered by data. It is a question that you ask people to realize a survey. It is not a question about only one person or thing. We have to be able to calculate an average.

    Example : How old are the students of our class ?
    Wrong example: How old is he ?

    There are two types of statisticals questions :
    --> opened : You can answer whatever you want
    Example : What is the favorite color of the students of our class ?
    --> closed : You have to choose in a list of answers
    Example : Do the students like our school ? YES NO
