Study Notes

Experimental Research Strategy

The goal of the experimental research strategy is to establish cause-and-effect relationships between variables.
A true experiment must demonstrate causality, internal validity, and control over extraneous variables.
In an experiment, a variable (independent variable) causes a change in another variable (dependent variable).
The experimental research strategy aims to establish a cause-and-effect relationship between the independent variable and the dependent variable.
An experimental research strategy must demonstrate that changes in the independent variable are the cause of changes in the dependent variable, and not the result of other factors.
