Front

What is a nonlinear association in a scatter plot?

Back

A nonlinear association is when the relationship between the variables cannot be represented by a straight line.

Front

How can you identify a negative relationship in a scatter plot?

Back

A negative relationship is identified when the data points trend downwards from left to right.

What does it mean if a scatter plot has outliers?

Back

Outliers are points that are far outside the main cluster of points and can affect the overall interpretation of the data.
