1. How do the three criteria for an experimental design, manipulation, randomization, and control minimize bias and decrease threats to internal validity? 2. Why do researchers state that randomized clinical trials provide the strongest evidence for an individual study when using an evidence-based model? 3. How does intervention fidelity increase the strength and quality of the evidence provided by the findings of a study using these types of designs? 4. What is your cosmic question?

These questions do not have data. These are conceptual, it is just asking on a basis of how would you do this in most generic forms of these questions. A) How would you solve for the “PMT” in an annuity and perpetuity problem? B) How would you determine which of the 3 “PMTs” you need to solve for? C) What would the time subscripts in the PVA and PVP formulas tell us? D) How would you solve for targeted savings...

Section 1. The following questions are conceptual questions based on chapters 1 and 2 (weeks 1 and 2 of the lecture notes). • Suppose that a survey is being planned for purposes of estimating the average number of hours exercising daily by adults (18 years of age or older) living in a certain community. A list of all individuals living in the community is not available; however, a list of all households is available at the office of community clerk....
