What does a single case design typically employ in its methodology?

A single case design typically employs baseline logic to demonstrate variable effects. This methodology focuses on examining individual responses to interventions by establishing a baseline measurement before the introduction of any treatment or intervention. The purpose of the baseline is to collect data on the behavior or outcome of interest without any intervention, which provides a comparison point for assessing the impact of the treatment.

Once the intervention is applied, changes in the behavior can be observed and compared to the baseline data. This allows researchers or practitioners to ascertain whether the changes are likely due to the intervention rather than other factors. By utilizing baseline logic, practitioners can establish a clear causal relationship between the independent variable (the intervention) and the dependent variable (the behavior or outcome being measured).

This approach is particularly useful in educational settings where the focus is often on individualized interventions, allowing for detailed tracking of progress and the effectiveness of specific strategies.
