Back

A positive association indicates that as one variable increases, the other variable also tends to increase.

Front

What does a negative association in a scatter plot indicate?

Back

A negative association indicates that as one variable increases, the other variable tends to decrease.

Front

What does 'no association' mean in a scatter plot?

Back

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

Front

What is a positive correlation?

What is a negative correlation?

Back

A negative correlation is a relationship where one variable increases while the other decreases, often represented by a downward slope in a scatter plot.

What is a linear association?

Back

A linear association is a relationship between two variables that can be represented by a straight line on a scatter plot.

Front

What is a nonlinear association?

Back

A nonlinear association is a relationship between two variables that does not follow a straight line, indicating a more complex relationship.

Front

How can you identify a positive linear association in a scatter plot?

Back

A positive linear association is identified by points that cluster around an upward sloping line.

Front

How can you identify a negative linear association in a scatter plot?

Back

A negative linear association is identified by points that cluster around a downward sloping line.
