If a simple linear regression model is developed based on a sample where the independent and dependent variables are known to be positively related, then the sign of the slope regression coefficient will be positive also.

Simple Linear Regression

An analytical technique that utilizes a linear equation to depict the connection between a single independent variable and a dependent variable.

Independent Variables

Variables that are manipulated or controlled in an experiment to test the effects on dependent variables, without being influenced by other variables in the study.

Dependent Variables

Dependent variables are outcomes or responses whose changes are influenced by the manipulation of independent variables in an experimental setup.
