Three components help researchers control other variables in a single-case study: baseline measurements, repeated observations, and replication.

Question

Quizplus · Accepted Answer

Baseline measurements establish the participant's initial performance level and serve as a comparison point for later observations. Repeated observations enable researchers to track changes in behavior over time and to assess the effects of the intervention. Replication involves conducting the same study with the same participant or a different participant to determine if similar results are obtained. All three components help researchers control extraneous variables in a single-case study.
