Question

match each correlation coefficient to the appropriate scatter plot.
r = 0.5 r = -0.5

Explanation:

Step1: Identify trend direction (left plot)

As $x$ increases, $y$ tends to decrease, indicating a negative correlation, so this matches $r=-0.5$.

Step2: Identify trend direction (right plot)

As $x$ increases, $y$ tends to increase, indicating a positive correlation, so this matches $r=0.5$.

Step3: Confirm correlation strength

Both plots show a moderate linear relationship, consistent with the magnitude of $|r|=0.5$.

Answer:

• Left scatter plot: $r = -0.5$
• Right scatter plot: $r = 0.5$
