Methods of Data Collection

Active learning helps students see that data visualization is not just about drawing graphs. By handling real data sets and debating chart choices, they experience why correct methods matter for accurate storytelling.

Activity 01

• Gallery Walk
• 35 min · Whole Class

Gallery Walk: The Chart Gallery

Students create three different types of charts for the same data set (e.g., a bar, line, and pie chart). They display them around the room and use a gallery walk to vote on which chart makes the data easiest to understand and why.

Compare different methods of data collection for a given research question.

Facilitation Tip

During the Gallery Walk, arrange charts around the room so students physically move between examples, forcing them to compare formats side by side.

What to look for

Present students with three scenarios: 1) Tracking student attendance daily, 2) Understanding student opinions on a new school lunch menu, 3) Measuring the temperature in the schoolyard every hour. Ask students to write down one data collection method for each scenario and briefly explain why it is suitable.

Activity 02

• Inquiry Circle
• 30 min · Small Groups

Inquiry Circle: Misleading Media

Groups are given real-world examples of 'bad' graphs (e.g., truncated y-axes or inconsistent scales). They must work together to identify the 'trick' being used and redraw the graph to show the data more honestly.

Justify the choice of a specific data collection method based on its advantages and disadvantages.

Facilitation Tip

For Misleading Media, provide students with three deliberately flawed infographics to analyze in pairs before discussing the manipulation tactics used.

What to look for

Pose the question: 'If you wanted to find out how much time students in your class spend playing video games each week, what are the pros and cons of using a survey versus asking them to record it in a daily log?' Facilitate a class discussion where students compare the methods.

Activity 03

• Think-Pair-Share
• 20 min · Pairs

Think-Pair-Share: Infographic Design

Students are given a set of facts about water usage in Australia. They brainstorm in pairs which icons and colors would best represent this data in an infographic, then share their design choices with the class to discuss visual communication.

Design a simple survey to collect data on a school-related topic.

Facilitation Tip

Use the Think-Pair-Share for Infographic Design so students first work alone, then refine ideas with a partner before presenting their draft to the class.

What to look for

Give each student a card with a simple research question, e.g., 'What is the most popular sport played at recess?'. Ask them to design two survey questions to collect data for this question and state one potential challenge they might face when collecting the data.

A few notes on teaching this unit

Teachers find that students learn data visualization best when they grapple with real-world problems and audience needs. Avoid presenting chart rules as abstract facts; instead, let students discover them through trial and error with guided reflection. Research shows peer discussion clarifies why some visuals mislead more than others, so structured critique is essential.

Students will confidently select the right chart type for different data sets, explain their choices, and critique visual representations for clarity and fairness. They will also recognize how context changes the meaning of visual data.

Watch Out for These Misconceptions

• During the Gallery Walk, watch for students who assume all charts are interchangeable and do not notice how the data type dictates the best visualization.

  Have students record on their Gallery Walk sheets which data patterns each chart represents, then sort their notes into categories like 'change over time' and 'parts of a whole' to see the mismatch when a wrong chart is used.

• During the Misleading Media activity, observe that students focus only on the visual height of bars and assume the tallest always means 'best'.

  Ask pairs to annotate each example with sticky notes explaining what each bar represents, then compare contexts such as 'most pollution' versus 'highest test scores' to shift attention from height to meaning.
