Slide Deck

Decoding Deceptive Data

How can data trick us?

Welcome students and introduce the topic. Ask them to think about how data influences their daily lives.

The Power of Data

Data can be used to inform... or to misinform.

Today, we'll become Data Detectives!

Explain that data is powerful but can be used to mislead. Set the stage for why learning to identify deception is important.

Misleading Graphs: Truncated Axes

Look closely at this graph. What do you notice about the Y-axis (the vertical one)?

How does starting the axis above zero change our perception of the data?

Introduce the first type of deception: misleading graphs. Focus on truncated axes as a common example.

Misleading Graphs: Inconsistent Scales

What if the jumps between numbers aren't equal?

How can this make small differences look huge, or big differences look tiny?

Show another example of a misleading graph, perhaps with inconsistent scales or a manipulated visual.

Beware of Biased Samples

Who was asked? How were they asked?

If we only ask certain people, or ask in a leading way, our data won't tell the whole story.

Transition to biased samples. Explain what a sample is and how bias can creep into data collection.

Types of Bias

Think about:

  • Voluntary Response Bias: Only people who really care respond.
  • Convenience Sample: Only asking people nearby.
  • Leading Questions: Questions that push you towards an answer.

Provide examples of different types of bias, like voluntary response bias or convenience sampling, and discuss their impact.

Faulty Conclusions: Correlation vs. Causation

Just because two things happen at the same time, does one cause the other?

  • Correlation: Things happen together.
  • Causation: One thing makes the other happen.

Move on to faulty conclusions, emphasizing the difference between correlation and causation.

Ice Cream & Shark Attacks!

When ice cream sales go up, so do shark attacks.

Does eating ice cream cause shark attacks? Or is there a hidden factor?

Give a clear, memorable example of correlation vs. causation.

Data Detective Challenge!

Now it's your turn to put on your detective hats!

Analyze the data presentations in your Data Detective Worksheet and uncover the truth!

Introduce the worksheet and explain that students will apply their new detective skills.

Reflect and Conquer

What strategies will you use next time you see data?

Be a critical thinker, be a data detective!

Review the worksheet answers and facilitate a class discussion. Conclude by reinforcing the importance of critical data analysis.

Answer Key

Data Detective Answer Key

Instructions: This answer key provides explanations for the deceptive practices in each scenario and suggests how the data could be presented more accurately.

Scenario 1: The "Amazing" Sales Growth Graph

Original Presentation Analysis:

  • Deceptive Practice: Misleading Graph (Truncated Y-axis)
  • Explanation: The Y-axis (sales numbers) does not start at zero. It starts at a higher value, making the difference between month 1 and month 3 sales appear much larger and more dramatic than it actually is. This exaggerates the perceived sales growth.
  • How it Misleads: It creates a false impression of rapid and significant growth, aiming to impress stakeholders or customers with seemingly exponential success.

More Accurate Presentation:

  • Suggestion: Start the Y-axis at zero to provide a true visual representation of the sales figures. This will show the actual magnitude of growth without exaggeration.
  • Step-by-step thought process:
    1. Identify the visual impact: The steep line suggests huge growth.
    2. Examine the axes: Look at the numbers on the Y-axis. Do they start at zero? If not, it's a red flag.
    3. Calculate actual change: Determine the actual numerical increase to see if it matches the visual impression.
    4. Propose correction: Adjust the Y-axis to start at zero for an honest representation.

Scenario 2: The "Most Popular" Cereal Survey

Original Presentation Analysis:

  • Deceptive Practice: Biased Sample (Voluntary Response and Convenience Sample)
  • Explanation: The survey was conducted by asking customers at a single specialty organic grocery store to fill out a postcard. This is a voluntary response sample (only those motivated to respond will) and a convenience sample (only people at that specific store). People shopping at an organic store are likely to prefer organic or health-conscious cereals, leading to results that don't represent the general population.
  • How it Misleads: It falsely concludes that

15 minutes

Step 1

Introduction: What's Happening Inside?

5-10 minutes

  • Begin by asking students to share a time they felt a really strong emotion (excitement, frustration, sadness) and what it felt like in their bodies. (Ensure they understand they don't have to share personal details).
  • Introduce the idea that sometimes our emotions can feel big, like something is building up inside us.
  • Present the lesson's main question: "How can we manage our big feelings so they don't explode?"
  • Introduce the Volcano of Feelings Slide Deck (Slides 1-2).

Step 2

The Emotional Volcano Metaphor

15-20 minutes

  • Using the Volcano of Feelings Slide Deck (Slides 3-6), explain the volcano metaphor:
    • Base: Calm feelings, everyday emotions.
    • Building Pressure: Emotions start to grow (e.g., annoyance, worry).
    • Rumblings: Emotions get stronger, we might feel physical signs (e.g., tense muscles, fast heartbeat).
    • Eruption: The emotion becomes very intense, and we might act impulsively.
  • Engage students in a discussion: "What are some signs your emotional volcano is starting to rumble?" (e.g., frowning, clenching fists, loud voice).
  • Distribute the Emotional Volcano Worksheet. Guide students through identifying different emotions at each stage of the volcano and how they might feel physically and mentally. Encourage sharing and discussion.

Step 3

Cooling Down Strategies

15-20 minutes

  • Transition to how we can "cool down" our emotional volcanoes before they erupt, using the Volcano of Feelings Slide Deck (Slides 7-8).
  • Brainstorm a list of healthy coping strategies as a class (e.g., deep breaths, counting, talking to a trusted adult, drawing, taking a break, drinking water).
  • Introduce the Cooling Down Strategies Activity. Students will choose and illustrate a strategy or two that they think would work for them.
  • Have students share their chosen strategies and why they picked them.

Step 4

Reflection and Wrap-up

5-10 minutes

  • Facilitate a brief class discussion using prompts:
    • "What is one new way you learned to 'cool down' your emotional volcano today?"
    • "Why is it important to recognize our emotions when they are just 'rumbling'?"
  • Reiterate that it's okay to have big feelings, and everyone can learn to manage them.
  • Encourage students to practice the cooling down strategies they identified. (Slide 9)

Volcano of Feelings: Managing Emotional Eruptions

What happens when our feelings get BIG?

Greet students and start with a brief check-in. Ask students to think about how they feel today. Introduce the idea that we all have big feelings sometimes.

Our Emotional Volcano

Have you ever felt like your feelings were building up inside you?
Like a volcano getting ready to erupt?
Today, we'll learn how to understand and manage those big feelings!

Explain that today we'll learn about our feelings using a fun and helpful metaphor: a volcano!

The Calm Base: Everyday Feelings

At the bottom of our volcano are our everyday, calm feelings.
These are feelings like:
- Happy
- Content
- Curious

Introduce the base of the volcano: calm feelings. Ask students for examples of calm feelings.

Building Pressure: Feelings Start to Grow

Sometimes, feelings start to bubble up.
They might not be huge yet, but you can feel them growing.
- A little annoyed
- A bit worried
- Slightly frustrated

Explain how feelings start to build. Ask students what makes them feel a little annoyed or worried.

The Rumblings: Warning Signs!

Our volcano starts to rumble when feelings get stronger!
Your body might give you clues:
- Tense muscles
- Fast heartbeat
- Frowning
- Loud voice

Describe the 'rumbling' stage. Emphasize physical signs. Ask students how their body feels when they get upset.

The Eruption: Big Feelings Explode!

When feelings get too big, our emotional volcano can erupt!
This means our feelings come out very strongly.
- Yelling
- Crying
- Hitting (ourselves or others)
- Throwing things

Explain what an 'eruption' means for emotions. Stress that it's okay to feel this way, but we want to learn to prevent the eruption. Ask for examples of what an emotional eruption might look like (without naming specific students).

Cooling Down Our Volcano!

What can we do to stop our emotional volcano from erupting?
How can we "cool down" those big feelings?

Transition to cooling down strategies. Ask students for ideas before showing examples.

Powerful Cool-Down Strategies

Here are some ways to cool down:
- Take 3 deep breaths
- Count to 10
- Talk to a trusted adult
- Get a drink of water
- Draw or write about your feelings
- Take a walk or move your body

Present some strategies. Encourage students to think about which ones work best for them.

You've Got This!

It's okay to have big feelings!
The more we practice cooling down, the better we get at managing our emotional volcanoes.
Keep practicing your strategies!

End with a positive message about practicing these skills. Encourage them to try a strategy next time they feel their volcano rumbling.
