In a single-group design in which treatments are alternated (ABAB design), what is the purpose of conducting multiple initial observations before any treatment is given?
1. pretest researcher assumptions about the study sample
2. establish a baseline for comparison post-treatment
3. establish which group gets the initial “A” treatment
