Experimental Design and Reproducibility
Competency: Critique elements of experimental design and reporting for reproducibility and validity
- Explain the steps of the scientific method
- Describe the characteristics of quality scientific research
- Explain current threats to quality scientific research including lack of reproducibility, faulty experimental design, and pressure to publish
- Describe experimental design factors that impact experiment reproducibility
- Identify reporting factors that impact experimental reproducibility
