Upload by Noah

Unit 15, Lesson 1 guides students to understand and apply the statistical process by posing questions that anticipate variability in data. Learners examine the Statistical Cycle, describe statistical reasoning, and practice formulating statistical questions designed to produce useful information. The lesson connects earlier informal data experiences to reasoning about populations using samples, emphasizing representativeness and the role of random sampling. Students participate in graph analysis activities and reflect on how data collection supports decision-making.

This lesson builds on informal introductions to data in earlier units and begins to connect these ideas to the Statistical Cycle. | | | | LESSON OBJECTIVES | | | | At the end of this lesson, students will be able to: | | | | • examine the Statistical Cycle
• describe statistical reasoning
• pose statistical questions that are designed to provide information | | | | STANDARDS | | | | Citation | [*This portion of the standard will not be explicitly covered in this lesson.] | | | 6.SP.1 | Recognize a statistical question as one that anticipates variability in the data related to the question and accounts for it in the answer. | | | 7.SP.1 | Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences. | | | 1-3 MATHEMATICAL PRACTICE(S) ADDRESSED IN THIS LESSON | | ELEMENTS OF RIGOR | | MP 3: Construct viable arguments and critique the reasoning of others.
MP 4: Model with mathematics. | | Which aspect(s) of Rigor do the targeted Standard(s) require? Conceptual understanding of key concepts
Procedural skill and fluency
Rigorous application of mathematics in real-world contexts | | ESSENTIAL QUESTIONS | | --- | | Why is data collection and analysis important? How does it affect me? How do I go about creating my own statistical information? | | EVIDENCE OF LEARNING | | Ways I and my students will know the extent to which the objectives have been met. | | Students will be able to develop appropriate questions based on desired information. | | LEARNING PLAN-Vocabulary | | | | --- | --- | --- | | statistics

Show just one or two graphs from a site such as [https://www.statcrunch.com/5.0/viewreport.php?reportid=62506](https://www.statcrunch.com/5.0/viewreport.php?reportid=62506. Ask)[. Ask](https://www.statcrunch.com/5.0/viewreport.php?reportid=62506. Ask) students (in pairs) to think about what questions were asked and how the data were collected for each of the graphs.[The statcrunch.com site provides some information about who was asked and what the exact questions were. These could be shared with students after they reason for themselves.] | A couple of graphs with title and data only, no accompanying explanation about the data | | | 2. Once students share their thinking, ask:
• Do you think these data are accurate? Why or why not?
• What do you think would be the best way to collect data to answer such a question?
Note to teacher: There is not a right or wrong answer to any of these questions. You want students to begin to realize that they should be asking their own questions about data, which is what this unit isabout.
Segue: Ask students, Have you ever wondered where statistics such as “23% of Americans read a print newspaper daily” come from? Is it just made up? In this unit, you’re going to become a much more savvy consumer of data and statistics. | | | | --- | --- | --- | | LEARNING PLAN – Body of the Lesson | MATERIALS | TIME | | --- | --- | --- | | Statistical process | | | | 1. Begin by asking students where they think real statistics come from. Ask, What would be the process for figuring out who likes what? | | |

FAQs

What is the main skill students develop in Unit 15, Lesson 1?

Students learn to describe the statistical reasoning process and to pose statistical questions that are designed to provide information while accounting for variability in data.

How does the lesson use the Statistical Cycle?

Students review the cycle as a sequence of steps—posing a question, collecting data, analyzing distributions, and interpreting results—then discuss where decisions made in their lives fit within the cycle.

What idea about populations and samples is emphasized in the standards?

Students learn that statistics can inform about a population by using a representative sample, and that random sampling helps produce samples that support valid generalizations.
