What is an example of a multiple baseline design?

A multiple baseline design is a type of single-case research design used to assess the effectiveness of an intervention across different subjects, settings, or behaviors. For example, a researcher might study the impact of a new reading program on three different students with reading difficulties. The intervention could be introduced to each student at staggered intervals, allowing the researcher to observe changes in reading performance while controlling for other variables. This design helps to establish a causal relationship between the intervention and the observed outcomes.
