Learning Objectives

• DAT-2.A Describe what information can be extracted from data.
• DAT-2.C Identify the challenges associated with processing data.

Essential Knowledge

• DAT-2.A.1 Information is the collection of facts and patterns extracted from data.
• DAT-2.A.2 Data provide opportunities for identifying trends, make connections, and addressing problems.
• DAT-2-A.3 Digitally processed data may show correlation between variables. A correlation found in data does not necessarily indicate that a causal relationship exists. Additional research is needed to understand the exact nature of the relationship.
• DAT-2.A.4 Often, a single source does not contain the data needed to draw a conclusion. It may be necessary to combine data from a variety of sources to formulate a conclusion.
• DAT-2.C.1
• DAT-2.C.5 Problems of bias are often created by the type or source of data being collected. Bias is not eliminated by simply collecting more data.

0. Before class

• For the Select a Question activity:
  • You will need to prepare a "lottery" method for students to finalize their data research project question.
  • On slips of paper, write numbers for the number of students in your class.
  • Assign each student a number a slip of paper and select from those numbers to see who "wins".
  • Another option is to allow students who have the same question idea to work together as a pair.
• For the Bias in Survey Questions activity:
  • Print 10 copies of the Bias in Surveys Activity page, or
  • Add the Bias in Surveys Activity page to the Collaboration page.
  • Be prepared to assign each example of survey bias to one of the 10 groups that are formed when you reach this part of the lesson:
    • You can write each example on a slip of paper to give the students, or
    • You can simply walk around the room and tell each group a number 1-10.

1. Student reflection (5 minutes)

• Encourage students to reflect on topics considering the following:
  • Who would you need to survey to help answer your questions? (teens, parents, etc.)
  • How many people in that group could you get to complete your survey?
  • Which topic interests you the most?

2. Pair and share (5 minutes)

• Encourage students to talk to a classmate about their topics:
  • What are your possible topics?
  • Which one do you think you will choose?
    • If you are considering one of the questions on the Prompt Ideas page, what is your back up question? (consider that question in the remaining questions as well)
  • Why do you want to choose that one?
  • Who will you survey?
  • Do you think you will have any challenges collecting data?
• Give classmate feedback on what you think about your partner's topic.

3. Select a question (10 minutes)

• Call out numbers and have students share their research data question.
• Record their questions to keep track of topics.

4. Data collection methods (5 minutes)

• Define quantitative vs qualitative data.
• Discuss the various methods for collecting data.

5. Survey creation tips (15 minutes)

• Discuss the different types of survey questions.
• Bias in Surveys activity:
  • Students should work with the peers sitting closest to them.
  • Organize 10 groups.
  • Assign each group one of the 10 examples of survey bias.
  • Ask students to follow the directions on the Bias in Surveys Activity page.
  • After a few minutes, ask each group to share what they learned about their example.
• Give students tips on creating a good survey.

6. Create survey questions (5 minutes)

• Students will begin crafting their survey questions in class.
• They will finish creating those questions for homework.
• Share the Survey Rubric with students so they know how you will grade their surveys.

7. Homework

• Students will finish writing their survey questions for homework
• Students must have all questions crafted by tomorrow to move on to the next step.
  • They will put them in Microsoft Forms tomorrow
