I wonder if, Do you like sports?is a statistical question.I wonder if, Do you like sports? is a statistical question?What makes a question a statistical question? 1Eric 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.In this lesson you will learn how to define a statistical question by comparing examples and non=examples.

Responses from 6th graders at McKinley Middle SchoolLets ReviewLets review by looking at the important elements of a graph. The title appears at the top and includes a summary of the question asked. Each of the bars are labeled and the y axis has a title, Subjects which summarizes the answers. The x-axis here is the number of students with the numbers spaced evenly and the axis title below. The population that was surveyed here is stated at the bottom.

3Students 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?A Common MistakeA common mistake that students make is asking questions that have too few or too many answers. Look at these questions and imagine what how the graphs might look. 4Do you like math?

Responses from 6th graders at McKinley Middle SchoolCore LessonLets begin with the question, Do you like math? When 6th graders at McKinley Middle School were asked this question, here were their responses. This is not a statistical question because there are only 2 possible answer choices yes or no. 5Change 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.

Responses from 6th graders at McKinley Middle SchoolCore LessonWhen the question is changed to What is your favorite subject in school? there are a variety of answers and interesting information is given. This is a great example of a statistical question.

Favorite Sports on TVWhat is your favorite sport on TV?Based upon U.S. viewer data from The Nielsen Company.Core LessonLets look at another question. What is your favorite sport on TV? Is this a statistical question? How much variability would you expect, in other words, how many answer choices would you expect? Here is how the graph looks. Was it what you expected? It includes an interesting question, the population that was surveyed, and variability in the responses.

Since the objective is comparing examples and non-examples, you should have a graph that is a non-example to help build the definition. What is your favorite sport on TV?

Responses from members of the University of Connecticut football teamCore LessonImagine how this data might be different if the people surveyed were the members of the University of Connecticut football team. How would you expect the graph to look? Not surprising, but all of the responses were for football. This had an interesting question and the population surveyed is stated, but there is no variability in the responses. This is not a statistical question. 9Change 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. A statistical question:Expects a variety of answers.Includes a specific population.Has variability in the responses.Core LessonA statistical question asks about a topic of interest, includes a specific population, and has variability in the responses.

Check slides. You did not use this objective in the Reviewing objective slide. 11This does not match the objective stated at the beginning. Which of these is a statistical question?What is your favorite flavor of ice cream?Is chocolate your favorite ice cream flavor?Guided PracticeTry this problem on your own. Which of these is a statistical question? Is chocolate your favorite ice cream flavor? or What is your favorite flavor of ice cream? Which question will give you a variety of answers? The first question asks a question in which the only answers are yes or no. The second question will bring many more responses, so it is a statistical question.12Which 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?Quick QuizLearnZillion Notes:--Quick Quiz is an easy way to check for student understanding at the end of a lesson. On this slide, youll simply display 2 problems that are similar to the previous examples. Thats it! You wont be recording a video of this slide and when teachers download the slides, theyll direct their students through the example on their own so you dont need to show an answer to the question.13In the lesson set, I recommended the questions be

How many miles do I live from school?

and

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

They are similar, but can focus on the variability of responses. 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?Quick QuizLearnZillion Notes:--Quick Quiz is an easy way to check for student understanding at the end of a lesson. On this slide, youll simply display 2 problems that are similar to the previous examples. Thats it! You wont be recording a video of this slide and when teachers download the slides, theyll direct their students through the example on their own so you dont need to show an answer to the question.14I would revised questions to be the following:

How many books did you read this summer? V. How many books did you read today?
