The researcher is using a <u>"multiple-baseline-across-settings"</u> design.
The multiple baseline design is valuable for intercessions that are irreversible because of learning impacts, and when treatment can't be pulled back. In this plan, behavior is estimated crosswise over either multiple individuals, behaviors, or settings.
For the multiple-baseline-across-behaviors design, various practices of a similar individual are considered.
