Scatterplots Form Direction Strength

When describing scatterplots you use the following 4 characteristics: Direction, Form, Strength, and Unusual Features. Match the definition to each characteristic:

• A scatterplot can show a linear or non-linear relationship

• Unusual Features

• A scatterplot can show a positive association, negative association, or no association

• Direction

• A scatterplot can show a weak, moderate, or strong association

• Strength

• Look for individual points that fall outside of the overall pattern

• Form

Guess the correlation:

• 0.67

• -0.083

• -0.792

• 0.42

A weak negative correlation has a r close to _______

• -1

• -0.49

• 0.93

• 0

Match the scatterplot to the correlation:

• r=0.304

• 
• r=-0.969

• 
• r=-0.344

• 
• r=0.765

•
