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

Front

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

Back

Front

What does no association mean in a scatter plot?

Back

No association means that there is no discernible relationship between the two variables; the points are scattered randomly.

Front

What is a nonlinear association?

Back

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

Front

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

Back

A positive association can be identified when the points slope upwards from left to right.

Front

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

Back

A negative association can be identified when the points slope downwards from left to right.

Front

What does it mean if the points in a scatter plot are tightly clustered around a line?

Back

It indicates a strong association between the two variables.

Front

What does it mean if the points in a scatter plot are widely scattered?

Back

It indicates a weak association between the two variables.

Front

What is the purpose of using scatter plots?

Back

Scatter plots are used to visually represent the relationship between two variables and to identify trends or patterns.
