Facilitating Each Lesson

Lesson 1: Truncated Axes and Stretched Scales

Tip: The most common trick: starting the y-axis above zero to make small differences look huge. Take time to let your child explore and share their thoughts.

Try asking: "What do you think about what a truncated y-axis is and why it misleads?"

Lesson 2: Cherry-Picking and Missing Context

Tip: Learn how selecting only favorable data points creates a false picture. Take time to let your child explore and share their thoughts.

Try asking: "What do you think about what cherry-picking means: showing only data that supports your argument?"

Lesson 3: Visual Tricks: 3D, Colors, and Proportions

Tip: Discover how 3D effects, color choices, and distorted proportions manipulate your perception. Take time to let your child explore and share their thoughts.

Try asking: "What do you think about 3d graphs: how depth makes bars look bigger or smaller?"

Lesson 4: Redesigning Misleading Graphs

Tip: Take misleading graphs and fix them. Make the same data tell an honest story. Take time to let your child explore and share their thoughts.

Try asking: "What do you think about principles of honest graph design?"
