Single Subject Research Design

What is the primary characteristic of ABAB design?

• Single exposure to one condition

• Random assignment to groups

• No control group

• 
  Repeated exposure to two different conditions

In ABAB design, what does the second 'A' represent?

• 
  Second trial

• First phase

• Second phase or condition

• Third condition

How does withdrawal design address the issue of stability of baseline data?

• By comparing baseline data with data collected during the withdrawal phase

• By comparing baseline data with data collected during the intervention phase

• 
  By ignoring baseline data completely

• By using a different method to collect withdrawal phase data

What is a dependent variable in a single subject research design?

• 
  The dependent variable is the variable being measured or observed.

• The dependent variable is the variable that remains constant throughout the study.

• The dependent variable is the variable that is controlled by the researcher.

• 
  The dependent variable is the variable being manipulated.

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

• 
  time, age, gender, location

• weather, food, clothing, hobbies

• language, culture, religion, education

• behavior, academic performance, mood, physiological responses

What is the difference between a dependent variable and an independent variable in single subject research?

• The dependent variable is controlled by the researcher, while the independent variable is influenced by external factors.

• 
  The independent variable is manipulated by the researcher, while the dependent variable is measured or observed.

• The dependent variable is manipulated by the researcher, while the independent variable is measured or observed.

• 
  The dependent variable is qualitative, while the independent variable is quantitative.

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

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

• Unmeasurable, unobservable, insensitive to change, and unrelated to the independent variable being studied.

• 
  Quantitative, objective, resistant to change, and indirectly related to the independent variable being studied.

• Qualitative, subjective, resistant to change, and indirectly related to the independent variable being studied.
