We want to decide if each of these questions is a statistical question or not.
00:11
So what we want to do is think about if we ask each member of this group that's going out for ice cream, would they each give the same answer or would they give different answers? so if we think of lynn and her friends answering the question, how far are we from the ice cream shop? well, they went together.
00:33
So maybe if we asked the first person, they would say, we're three blocks away.
00:38
What would the next person say? well, they would say they're three blocks away as well.
00:43
This group of people are going together, so all of their answers to how far are we from the ice cream shop would be the same.
00:51
That means a is not a statistical question.
00:58
How about b? what is the most popular ice cream flavor this week? maybe the first person we asked would say chocolate.
01:07
Maybe the next person would say rocky road.
01:11
Maybe the third person would say lemon swirl.
01:15
Each person is likely to have their own answer to this question, so this would be a statistical question.
01:26
Part c, what does a group of four people typically spend on ice cream at this shop? how would we answer this question? maybe we would walk around the shop asking different groups of four, how much they spent.
01:42
Maybe the first table spent $20.
01:46
Maybe the next table spent 10.
01:51
Each group of four people is likely to spend a different amount so we would get different answers because we have that variability, that changing of the answers from person to person who we ask, this is a statistic.
