7. O1 Ok Ok+1 O2k X1 Baseline Condition - A Experimental Condition - B Quasi-Experimental: Single SubjectA-B Design Single Subject methodology makes use of two conditions. The Baseline condition – A – and the Experimental Treatment condition – B and focuses on the behavior of an individual.

8. Quasi-Experimental: Single Subject/Multiple BaselineA-B-A-B Design The Multiple Baseline design allows one to study multiple effects & make multiple comparisons over time.
