How can you create a statistical question that has variability?
![Page 16: I wonder if, “Do you like sports?” is a statistical question.](https://reader035.fdocuments.net/reader035/viewer/2022062304/56649cdb5503460f949a5a70/html5/thumbnails/16.jpg)
Often students write questions with only two possible answers and do not

![Page 17: I wonder if, “Do you like sports?” is a statistical question.](https://reader035.fdocuments.net/reader035/viewer/2022062304/56649cdb5503460f949a5a70/html5/thumbnails/17.jpg)

Variability is the number of different answers you hear.
![Page 19: I wonder if, “Do you like sports?” is a statistical question.](https://reader035.fdocuments.net/reader035/viewer/2022062304/56649cdb5503460f949a5a70/html5/thumbnails/19.jpg)

To write a good statistical question:
Think about the different answers you expect to hear and edit your question.
Remember to state the population.
![Page 23: I wonder if, “Do you like sports?” is a statistical question.](https://reader035.fdocuments.net/reader035/viewer/2022062304/56649cdb5503460f949a5a70/html5/thumbnails/23.jpg)
Look at this question: “Do you like dogs?”
How many responses would you expect to hear? How could we rewrite it to account for more variability?
![Page 24: I wonder if, “Do you like sports?” is a statistical question.](https://reader035.fdocuments.net/reader035/viewer/2022062304/56649cdb5503460f949a5a70/html5/thumbnails/24.jpg)
Rewrite this question to make it a statistical question that accounts for variability:
“Do 6th graders at Peterson Middle School like apples or oranges?”
![Page 25: I wonder if, “Do you like sports?” is a statistical question.](https://reader035.fdocuments.net/reader035/viewer/2022062304/56649cdb5503460f949a5a70/html5/thumbnails/25.jpg)
Rewrite this question to make it a statistical question that accounts for variability:
“What street do residents of Alexandria live on?”
