Disc and article analysis

disc1,This week you are leaning about the hypothesis testing method in statistics. This process starts out by stating the null and alternative hypotheses. Review the terms in “The Visual Learner: Statistics,” located in the Topic 3 Resources, to answer these questions.

Think of a research study that you would like to conduct at your current or future place of employment. In designing your research question, describe the null and alternative hypotheses. What would type I and type II errors look like in this hypothetical situation? Identify if this was a one-tailed or a two-tailed test?

Example: It is hypothesized that a follow-up phone call 2 weeks after discharge will improve patient compliance with the aftercare protocol.

Null Hypothesis: Communication with the patient 2 weeks after discharge will not change the compliance of patient aftercare protocol.

Alternative Hypothesis: Communication with the patient 2 weeks after discharge will improve compliance of patient aftercare protocol.

Type I Error: A type I error could occur if the data suggest an effect of the postdischarge phone call when there was not improvement in compliance of the aftercare protocol.

Type II Error: A type II error could have occurred if the data suggest that there was no improvement in compliance of the aftercare protocol when in fact there was an improvement.

One- or Two-Tailed Test: This is a one-tailed test because the researchers are predicting an increase in compliance of the aftercare protocol.

Initial discussion question posts should be a minimum of 200 words and include at least two references cited using APA format. Responses to peers or faculty should be 100-150 words and include one reference.

Disc,2 , What information does a hypothesis test provide versus a confidence interval? How is this utilized in health care research? Provide a workplace example that illustrates your ideas. If you are not currently working in health care, to answer this question, research a local hospital or health care organization and provide an example of how they utilize inferential statistics.

Initial discussion question posts should be a minimum of 200 words and include at least two references cited using APA format. Responses to peers or faculty should be 100-150 words and include one reference.

3, ARTICLE ANALYSIS. Search the GCU Library and find two new health care articles that use quantitative research. Do not use articles from a previous assignment or articles that appear in the topic Resources or textbook.

Complete an article analysis for each using the “Article Analysis 2” template.

Refer to “Patient Preference and Satisfaction in Hospital-at-Home and Usual Hospital Care for COPD Exacerbations: Results of a Randomised Controlled Trial” in conjunction with “Article Analysis: Example 2,” 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. A link to the LopesWrite technical support articles is located in Class Resources if you need assistance.

Sampling Method
Mixed methods; quantitative was randomized sampling.
How Were the Data
Collected?
A questionnaire with both open-ended questions and questions with a scale of 1-5
(p. 1539)
70 from the early assisted discharge care group (p. 1540).

Inferential Statistics
The Mann-Whitney tests were used to analyze the second part of the survey.
Clearly identify which
hypothesis tests were
used and the results.
The third part used a chi-square test and regression analysis.
Assess the
Appropriateness of
Statistical Methods
Used in This Study
The data meet the assumptions for the test, including sample size used, and
address the general hypothesis statements. The data are nonparametric and
therefor these two nonparametric tests are appropriate for the analysis of the data.
The researcher justified the analysis in the choice of test in the analysis section.
Provide rationale to
support your response.
