Minimizing bias and decreasing threats to internal validity is important to experimental designs.

Minimizing bias and decreasing threats to internal validity is important to experimental designs.

Discussion Forum 4: Critical Thinking

1. Minimizing bias and decreasing threats to internal validity is important to experimental designs. How will a researcher use the three criteria, manipulation, randomization, and control to minimize bias and decrease threats to internal validity?

2. Many times, researchers state that randomized clinical trials (RCT) provide the strongest level of evidence for an individual study when using an evidence-based model.  As a researcher, why do you think this statement is true?

3. When conducting an experimental design, how will you as a researcher, use intervention fidelity to increase the strength and quality of the evidence provided by the findings of the study?

4. What is your cosmic question? (This is a question you ask your peers to respond to based on the chapter discussed in class this week i.e. Quantitative studies).
