To identify statistical questions, we should look for questions that require data collection and analysis of a group (in this case, Dan's friends) rather than questions that seek a single, definitive answer about an individual.
Here are the questions from your list that are statistical:
-
What time of the day do my friends eat their biggest meal? - This question could yield different answers from different friends, making it statistical.
-
How many times each week do my friends eat out? - Again, this question asks for a frequency that can vary among the group and can be analyzed statistically.
-
What types of foods do my friends prefer? - This question would gather data on different preferences, making it statistical.
The following questions are NOT statistical questions because they pertain to a single individual:
-
Does Thomas like to eat out? - This is a yes or no question about one person.
-
What is George's favorite food? - This also pertains to a single individual's preference.
So, the correct statistical questions Dan could ask are:
- What time of the day do my friends eat their biggest meal?
- How many times each week do my friends eat out?
- What types of foods do my friends prefer?
