What does 'no association' mean in the context of scatterplots?

Back

'No association' means that there is no discernible relationship between the two variables; changes in one variable do not predict changes in the other.

How can you identify a linear positive association in a scatterplot?

Back

A linear positive association is identified when the points on the scatterplot slope upwards from left to right.

Front

How can you identify a linear negative association in a scatterplot?

Back

A linear negative association is identified when the points on the scatterplot slope downwards from left to right.

What is the significance of outliers in a scatterplot?

Back

Outliers are points that fall far away from the other data points and can significantly affect the interpretation of the association.

What does it mean if a scatterplot shows a cluster of points?

Back

A cluster of points indicates that there is a concentration of data points in that area, suggesting a stronger relationship between the variables.
