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

Back

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

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

Back

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

Front

What does it mean if a scatterplot has ordered pairs with no predictable pattern?

Back

It means that the scatterplot has no association, indicating that the variables do not influence each other.
