ABSTRACT

One possible small sample size solution is obtained by conceptualizing a study with a small sample size as a set of replicated single-case experiments. Single-case experiments are experiments in which one unit is observed repeatedly during a certain period of time under different levels of at least one manipulated variable. These experiments can have a randomized design and can be replicated for a preplanned number of participants. The statistical analysis of the data collected with these experiments can be model- or design-based, and can be unilevel or multilevel. This chapter provides an example of a unilevel design-based analysis.
