What is a linear relationship in a scatterplot?

Back

A linear relationship is when the data points form a straight line, indicating a consistent rate of change between the variables.

Front

What is a nonlinear relationship in a scatterplot?

Back

A nonlinear relationship is when the data points do not form a straight line, indicating that the rate of change between the variables varies.

Front

What does a strong correlation mean?

Back

A strong correlation means that the data points are closely clustered around a line, indicating a strong relationship between the variables.

Front

What does a weak correlation mean?

Back

A weak correlation means that the data points are more spread out and do not closely follow a line, indicating a weaker relationship between the variables.

Front

How can you identify a positive correlation in a scatterplot?

Back

You can identify a positive correlation if the data points trend upwards from left to right.
