Single Subject Research Design - Dependent Variable

Front

What is a dependent variable in single subject research design?

Back

The dependent variable is the variable being measured or observed.

Front

Why is it important to clearly define the dependent variable in a single subject research design?

Back

To accurately measure and evaluate the effects of the independent variable on the participant's behavior or outcome.

Front

How can the reliability and validity of the dependent variable be ensured in single subject research?

Back

By using multiple measures, establishing clear operational definitions, conducting inter-rater reliability checks, and using control conditions.

Front

What are the characteristics of a good dependent variable in single subject research?

Back

Measurable, observable, sensitive to change, and directly related to the independent variable being studied.

Front

What are some common examples of dependent variables in single subject research?

Back

Behavior, academic performance, mood, physiological responses.

Front

What is the role of the independent variable in single subject research design?

Back

The independent variable is the variable that is manipulated to observe its effect on the dependent variable.

Front

How does operational definition impact the measurement of the dependent variable?

Back

Operational definitions provide clear criteria for measurement, ensuring consistency and clarity in what is being observed.

Front

What is inter-rater reliability and why is it important in single subject research?

Back

Inter-rater reliability assesses the degree to which different observers agree on the measurements of the dependent variable, ensuring the reliability of the data.

Front

What is the significance of using control conditions in single subject research?

Back

Control conditions help to isolate the effects of the independent variable by providing a baseline for comparison.

Front

How can sensitivity to change be assessed in a dependent variable?

Back

Sensitivity to change can be assessed by using instruments that can detect small variations in the dependent variable over time.
