Interpreting Scatter Plots: Linear or Nonlinear Relationships

This lesson teaches how to interpret scatter plots by identifying if they are linear or nonlinear. Linear plots form a straight line, while nonlinear plots form a curve. Examples include comparing a square's side length to its perimeter (linear) and area (nonlinear), and a ball's height over time (nonlinear). The lesson emphasizes that not all real-world relationships are linear.

What is a common mistake when interpreting scatter plots?

• Believing scatter plots have no pattern

• Assuming all scatter plots are nonlinear

• Assuming scatter plots are always circular

• Thinking all scatter plots are linear

What does a linear scatter plot look like?

• A circular pattern

• A series of random points

• A zigzag pattern

• A straight line

How does the perimeter of a square change as the side length increases?

• It decreases

• It remains constant

• It forms a curve

• It increases by the same factor

Why does the area of a square form a curved pattern as the side length increases?

• The area decreases at a constant rate

• The area increases at a constant rate

• The area increases at a varying rate

• The area remains constant

What kind of pattern does the trajectory of a thrown ball form?

• A straight line

• A zigzag pattern

• A circular pattern

• A curved pattern
