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.
