Questions and Answers

What is the difference between measured and manipulated variables in research?

Measured variables are controlled by the researcher, while manipulated variables are observed and recorded

Measured variables cannot be controlled by the researcher, while manipulated variables are observed and recorded

There is no difference between measured and manipulated variables.

Measured variables are observed and recorded, while manipulated variables are controlled by the researcher. (correct)

What are conceptual variables and how are they defined?

Conceptual variables are abstract concepts, and are defined using operational definitions.

Conceptual variables are specific ways of gathering data, and are defined using operational definitions.

Conceptual variables are abstract concepts, and are defined using conceptual definitions. (correct)

Conceptual variables are specific ways of gathering data, and are defined using conceptual definitions.

What is the importance of defining variables at the theoretical level in research?

It ensures that all variables are measurable and can be observed

It prevents the need for operational definitions of variables.

It helps researchers to manipulate variables more effectively.

It helps to establish clear hypotheses and research questions. (correct)

Study Notes

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.
