  1. I wonder if, “Do you like sports?” is a statistical question.

  2. In this lesson you will learn how to define a statistical question by comparing examples and non-examples.

  3. Responses from 6th graders at McKinley Middle School

  4. Students ask questions with too few or too many answers and do not state a specific population. What do you like best about school? Do you like math?

  10. A statistical question: • Expects a variety of answers. • Includes a specific population. • Has variability in the responses.

  11. In this lesson you have learned how to define a statistical question by comparing examples and non-examples.

  12. Which of these is a statistical question? What is your favorite flavor of ice cream? Is chocolate your favorite ice cream flavor?

  13. Which of these is a statistical question? How many miles do I live from school? How many miles do the students in my school live from school?

  14. Which of these is a statistical question? How many books did the students at Roberts Middle School read this summer? How many books did you read today?

  15. How can you create a statistical question that has variability?

  16. Often students write questions with only two possible answers and do not state the population. “Do you like listening to music?” Yes or No.

  17. “Do you like listening to music?” What is 6th graders’ favorite type of music? Who is Room 16’s favorite singer? How many hours per week do 6th graders listen to music?

  18. Variability is the number of different answers you hear.

  19. How many answers could you expect to hear if you asked 16 sixth graders at Taylor Middle School this question: What did you eat for dinner last night?

  20. “What did you eat for dinner last night?” What is the 6th graders’ favorite meal in the school cafeteria? What is the favorite Mexican food at Taylor Middle School?

  21. To write a good statistical question: Think about the different answers you expect to hear and edit your question. Remember to state the population.

  22. Look at this question: “Do you like dogs?” Howmany responses would you expect to hear? How could we rewrite it to account for more variability?

  23. Rewrite this question to make it a statistical question that accounts for variability: “Do 6th graders at Peterson Middle School like apples or oranges?”

  24. Rewrite this question to make it a statistical question that accounts for variability: “What street do residents of Alexandria live on?”

  25. Write 5 Statistical Questions?
