Scatter Plot, Trend Lines, Two-Way Table and Frequency Tables

As the age of the car increases, its value decreases. Which scatter plot represents this relationship?

• A

• B

• C

• D

You are analyzing a scatter plot that has a negative correlation. What is true of the of the x and y values?

• As x increases, y decreases

• As x increases, y increases

• As x decreases, y decreases

Describe the correlation in the graph shown.

• Strong Negative

• Strong Positive

• Weak Negative

• Weak Positive

Which best describes the form of this scatterplot?

• linear

• nonlinear

• scattered

If a scatterplot has no correlation then...

• ...it has no ordered pairs

• ...it has ordered pairs that have a negative pattern

• ...its ordered pairs have no predictable pattern

• ...if it makes a lion on a graph (roar!)
