Test Your Knowledge of Variables and Definitions in Research

• Researchers measure or manipulate variables in studies.
• Measured variables are observed and recorded, while manipulated variables are controlled by the researcher.
• Some variables cannot be manipulated, such as age and IQ.
• Variables that could put physical or emotional well-being at risk cannot be manipulated for ethical reasons.
• Some variables can be either manipulated or measured.
• Conceptual variables are abstract concepts, while operational definitions are specific ways of gathering data.
• Conceptual definitions are used to define conceptual variables.
• Operational definitions are used to turn a concept of interest into a measured or manipulated variable.
• Researchers must carefully define variables at the theoretical level.
• Empirical research involves testing hypotheses using operational definitions of variables.
