2. Why do researchers state that randomized clinical trials provide the strongest evidence for an individual study when using an evidence-based model?
Homework Answers
Randomized clinical trials provide the strongest evidence for an individual study when using an evidence-based model as they negate the effect of the confounding factors. Further, it is; conceptually easier to attribute any observed effect to the treatments being compared in a randomized clinical trial.

7. Do diet sodas contribute to obesity? Researchers recruited 1,200 randomly selected college students at state universities in Texas to participate in a four- year study looking at the relationship between diet soda and obesity. At the start of the study, students were weighed and interviewed. After interviews w the students, participants were classified as either regular soda drinkers, diet soda drinkers, or non-soda drinkers. Four years after the interview, the students were contacted again and reweighed. The weight gains...
