What is a linear relationship in a scatter plot?

Back

A linear relationship is when the data points can be approximated by a straight line, indicating a constant rate of change.

What is a nonlinear relationship in a scatter plot?

Back

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

What does it mean if a scatter plot has a weak correlation?

Back

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