PS561 Unit 5 Discussion
Characteristics of Single-Case Experimental Designs
This week, you have learned about the characteristics of SCEDs, including how they differ from traditional group design research and the strengths of each. You have also been introduced to the types of SCED graphs and what features of the design contribute to the determination of experimental control within evidence-based practices, along with the importance that internal and external validity have within SCED.
Please respond to the following:
- Provide a discussion that compares and contrasts the differences between single-case experimental designs (SCED) and group research designs used to investigate the effectiveness of interventions (e.g., studying a problem in an applied setting).
- Make sure to include a detailed description of the characteristics of SCED, including the considerations regarding internal and external validity.
- Explain the primary purpose of a comparative, component, and parametric analysis, and provide an original example of how each might be used as part of a single-case experimental design and incorporated purposefully into a practical intervention plan.
Review two of your classmates' responses, using the following ideas as a guide:
- Were each of the key points addressed regarding SCED vs. group designs? If not, what can you add to the response for your classmate to consider?
- Provide feedback on the practical examples of comparative, component, and parametric analysis.
- Ask at least one thoughtful follow-up question.
