Eureka Math Grade 6 Module 6 Lesson 22 Exploratory Challenge Answer Key

A statistical study involves the following four-step investigative process:

Step 1: Pose a question that can be answered by data.
Step 2: Collect appropriate data.
Step 3: Summarize the data with graphs and numerical summaries.
Step 4: Answer the question posed in Step 1 using the numerical summaries and graphs.

Now it is your turn to be a researcher and to present your own statistical study. In Lesson 17, you posed a statistical question, proposed a plan to collect data to answer the question, and collected the data. In Lesson 21, you created a poster or an outline of a presentation that included the following: the statistical question, the plan you used to collect the data, graphs and numerical summaries of the data, and an answer to the statistical question based on your data. Use the following table to organize your presentation.

Points to Consider: Notes to Include in Your Presentation:
(1)   Describe your statistical question.
(2)   Explain to your audience why you were interested in this question.
(3)   Explain the plan you used to collect the data.
(4)   Explain how you organized the data you collected.
(5)   Explain the graphs you prepared for your presentation and why you made these graphs.
(6)   Explain what measure of center and what measure of variability you selected to summarize your study.  Explain why you selected these measures.
(7)   Describe what you learned from the data.  (Be sure to include an answer to the question from Step (1) on the previous page.)

Answer:

Points to Consider: Notes to Include in Your Presentation:
(1)   Describe your statistical question. “My statistical question is ….”
(2)   Explain to your audience why you were interested in this question. “I am interested in finding an answer to this question because ….”
(3)   Explain the plan you used to collect the data. “My plan for collecting data to answer my question was ….”

“I was able to collect my data as planned.”  (If you were not able to collect the data, explain why.)  Explain any challenges or unexpected reactions in collecting your data.

(4)   Explain how you organized the data you collected. “Let me explain how I organized my data and prepared my summaries.”

Students might use a table to summarize the data or organize data in a list that could be used to prepare a dot plot or a box plot.

(5)   Explain the graphs you prepared for your presentation and why you made these graphs. “I developed a dot plot to start my statistical study because ….”
(6)   Explain what measure of center and what measure of variability you selected to summarize your study.  Explain why you selected these measures. “I selected (the mean or the median) as the measure of center because ….”

 

(7)   Describe what you learned from the data.  (Be sure to include an answer to the question from Step (1) on the previous page.) “Let me tell you the answer to my statistical question ….”
