In empirical work, randomization is seen as an effective means of controlling for potential biases. This thesis reviews the Journal of Applied Behavior Analysis (JABA) multiple baseline design articles from 1968-2017 to identify if and how articles randomize their participants, phases, trials, settings, or other factors. In this review, we suggest the requirement of randomization in multiple baseline design articles that is determined prior to the start of baseline to improve internal validity.
