Question

Quizplus · Accepted Answer

An A-B single case experimental design involves an initial baseline period (A) followed by a treatment or intervention period (B). It is used when removing the treatment (which would be necessary for an A-B-A design, where the treatment is withdrawn in the second A phase) might result in harm to the participant, making it unethical or impractical to revert to a no-treatment condition.
