NRS 428 Topic 2: Population and Sampling Distributions
Topic 2: Population and Sampling Distributions
Topic 2 DQ 1
Select a research article, other than the articles from your assignments, from the GCU library. Provide an overview of the study and describe the strategy that was used to select the sample from the population. Evaluate the effectiveness of the sampling method selected. Provide support for your answer. Include the article title and permalink in your post.
Topic 2 DQ 2
Using the research article selected for DQ 1, identify three key questions you will ask and answer when reading the research study and why these questions are important. When responding to peers, provide other questions and answers that could be considered in relation to the peers’ studies.
Article Analysis 1
The interpretation of research in health care is essential to decision making. By understanding research, health care providers can identify risk factors, trends, outcomes for treatment, health care costs and best practices. To be effective in evaluating and interpreting research, the reader must first understand how to interpret the findings. You will practice article analysis in Topics 2, 3, and 5.
For this assignment:
Search the GCU Library and find three different health care articles that use quantitative research. Do not use articles that appear in the Topic Materials or textbook. Complete an article analysis for each using the “Article Analysis 1” template.
Refer to the “Patient Preference and Satisfaction in Hospital-at-Home and Usual Hospital Care for COPD Exacerbations: Results of a Randomised Controlled Trial,” in conjunction with the “Article Analysis Example 1,” for an example of an article analysis.
While APA style is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines, which can be found in the APA Style Guide, located in the Student Success Center.
This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.
You are required to submit this assignment to LopesWrite. Refer to the for assistance.

|Broad Topic Area/Title||The differences in preference and satisfaction based upon hospital care location for COPD exacerbations|
|Variables and Type of Data for the Variables
|Treatment Location-categorical -“home treatment” and “hospital treatment”
Satisfaction – Ordinal Scale (1-5)
Preference – categorical “home treatment” and “hospital treatment”
|Population of Interest for the Study||COPD exacerbation patients from five hospitals and three home care organizations|
69 from the usual hospital care group
70 from the early assisted discharge care group
