Watch Voice of the Researcher for chapter 15. Answers the following questions

Setting the stage for discussion: In order for students to critique the rigor of a quantitative study, they should consider the generalizability of results, the interpretation of the results, and the study limitations, along with suggestions for future research and the impact the study has on the care provided by nurses. The following discussion will help students understand some of those considerations.

1. Dr. Sandau stressed that a power analysis is important in order to determine an adequate sample size and funding requirements. Did Dr. Sandau’s answer surprise you? Explain why or why not.

2. Dr. Sandau discussed generalizing the results of a study to other populations. The Fiedler et al. (2014) study sampled registered nurses at a large urban academic medical center in the Midwest. Can the results of this nurse residency study be generalized to other hospitals? Defend your answer.

3. Using Dr. Sandau’s definition of bias, describe what bias occurred in the Fielder et al.(2014) study.

4. Dr. Sandau mentioned that the absence of a statistically significant result was likely the result of a small sample size or use of an incorrect measurement tool. What other reasons might exist for results that are not statistically significant?

5. How can the limitations mentioned in the Fielder et al. (2014) study be eliminated in a replication study?
