I wonder if, “Do you like sports?”

is a statistical question.

Teacher

Eric has been recommending that the hook question be a question that is later answered in the Core Lesson or Guided Practice, so it makes a link and the lesson comes full circle. For example. "I wonder if, "What's your favorite sport? is a statistical question."

In this lesson you will learn how to define a statistical

question by comparing examples and non-examples.

Let’s Review

Responses from 6th graders at McKinley Middle School

A Common Mistake

Students ask questions with too few or too many answers and do not state a

specific population.

Do you like math?

What do you like best about

school?

Core Lesson Do you like math?


Teacher

Change the font in graph to Orly Font 2.Since the objective is comparing examples and non-examples, you should have a graph that is a non-example to help build the definition.

In this lesson you have learned how to define a statistical

question by comparing examples and non-examples.

This does not match the objective stated at the beginning.

Guided Practice

Which of these is a statistical question?

ice cream flavor?

Quick Quiz


How many miles do I live from school?

How many miles do the students in my school live from school?

Teacher

In the lesson set, I recommended the questions be How many miles do I live from school?andHow many miles do the students in my school live from school? They are similar, but can focus on the variability of responses.

Quick Quiz


How many books did the students at Roberts Middle School read this summer?

How many books did you read today?

Teacher

I would revised questions to be the following:How many books did you read this summer? V. How many books did you read today? We want to compare the variability of answers.

How can you create a statistical question that has variability?

Often students write questions with only two possible answers and do not

state the population.

“Do you like listening to music?”

Yes or No.

“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?

Variability is the number of different answers you hear.

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?

“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?

To write a good statistical question:

Think about the different answers you expect to hear and edit your question.

Remember to state the population.

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?

Rewrite this question to make it a statistical question that accounts for variability:

“Do 6th graders at Peterson Middle School like apples or oranges?”

Rewrite this question to make it a statistical question that accounts for variability:

“What street do residents of Alexandria live on?”

Write 5 Statistical Questions?

I would revised questions to be the following:How many books did you read this summer? V. How many books did you read today? We want to compare the variability of answers.
