Exploring the fundamentals of variables in research, this overview highlights the roles of independent and dependent variables in experimental studies. It delves into how researchers manipulate the independent variable to observe effects on the dependent variable, and the importance of controlling extraneous and confounding variables. Operationalisation of variables for precise measurement and study replication is also discussed, emphasizing the need for clarity in scientific inquiry.

The process of defining variables in measurable terms to ensure clarity and replicability in research
The deliberate variation of the independent variable to observe its effect on the dependent variable
Variables are crucial in experimental research as they allow for the observation of cause-and-effect relationships
Proper manipulation and control of variables ensure the validity and reliability of research outcomes
Operationalisation of variables allows for the reproduction of research by other investigators
