Check Your Understanding

1. How do 3D effects mislead?

Answer: 3D perspective makes front bars look larger and back bars look smaller, even if they represent the same value. It distorts comparison.

2. How can colors be used to mislead?

Answer: Bright, warm colors (red, orange) draw attention and seem more important. Dull gray minimizes categories. Strategic color choice can make one category seem dominant.

3. What is pictograph distortion?

Answer: When pictograph symbols are made bigger in two dimensions (width AND height), they look much larger than they should. Doubling height and width makes an image 4x larger visually.

4. Why should you be suspicious of fancy-looking graphs?

Answer: Because fancy effects often hide simple data. The more visual tricks a graph uses, the more likely it is trying to distract from what the data actually says.
