1. Minimizing bias and decreasing threats to internal validity is  important to experimental designs. Explain how a researcher uses  manipulation, randomization, and control to minimize bias and decrease  threats to internal validity.

2. Many times, researchers state  that randomized control trials (RCT) provide the strongest level of  evidence for an individual study. As a consumer of research, do you think this statement is true? Why or why not?

3.  When conducting an experimental study, discuss how the researcher will  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 will ask your peers to respond to based on the this week’s topic of Quantitative Research.)
