Simple linear regression is a statistical method that allows us to summarize and study relationships between two continuous (quantitative) variables:

$\Rightarrow$ One variable, denoted $x,$ is regarded as the predictor, explanatory, or independent variable.

$\Rightarrow$ The other variable, denoted $y$, is regarded as the response, outcome, or dependent variable.
