Front

What does a negative linear association in a scatter plot indicate?

Back

A negative linear association indicates that as one variable increases, the other variable decreases.

What does 'no association' mean in the context of scatter plots?

Back

Front

What is a nonlinear association?

Back

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

Front

How can you identify a positive correlation in a scatter plot?

Back

A positive correlation is identified when the data points trend upwards from left to right.

Front

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

Back

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

Front

What is the purpose of making predictions using a scatter plot?

Back

The purpose is to estimate the value of one variable based on the known value of another variable.

Front

What does it mean if two quantities have a positive correlation?

Back

If two quantities have a positive correlation, it means that as one quantity increases, the other quantity also increases.

Front

What does it mean if two quantities have a negative correlation?

Back

If two quantities have a negative correlation, it means that as one quantity increases, the other quantity decreases.
