What is a reason that alternating treatment designs may have good internal validity?
 
  A. The patterns of response vary with the alternating treatment conditions, so there is minimal overlap among data in the conditions.
   B. If one treatment is consistently associated with an improved level of responding, then the design demonstrates good experimental control.
   C. It does not provide replication of the relative effects of the different treatments.
   D. Both A and B

Question 2

Why is replication so important to a single subject research study? How many replications are needed?
 
  What will be an ideal response?

Answer to Question 1

D

Answer to Question 2

Replication refers to a repeated demonstration of the functional relationship between the independent and dependent variables. In other words, within the study, the researchers demonstrate more than once that the independent variable has a predictable and verifiable influence on the target behavior. Horner et al. (2005) suggested that 3 replications of the functional relationship was an indicator of a quality study. Clearly, at least 2 replications are needed.
