What does a negative association in a scatterplot indicate?

What is the y-axis typically used for in a scatterplot?

Back

The y-axis is typically used to represent the dependent variable.

Front

What does the slope of the trend line in a scatterplot indicate?

Back

The slope indicates the direction and strength of the relationship between the two variables.

Front

How can outliers affect a scatterplot?

Back

Outliers can skew the interpretation of the relationship, making it appear stronger or weaker than it actually is.
