__What are the Data Saying?__

- Set up your IBM SPSS account and run several statistical outputs based on the “SPSS Database” Use “Setting Up My SPSS” to set up your SPSS program on your computer or device. You may also use programs such as Laerd Statistics or Intellectus, if you subscribe to them.
- The patient outcome or dependent variables and the level of measurement must be displayed in a comparison table which you will provide as an Appendix to the paper. Refer to the “Comparison Table of the Variable’s Level of Measurement.”
- Submit a 1,000-1,250 word data analysis paper outlining the procedures used to analyze the parametric and non-parametric variables in the mock data, the statistics reported, and a conclusion of the results.

Provide a conclusive result of the data analyses based on the guidelines below for statistical significance.

**PAIRED SAMPLE T-TEST:**Identify the variables**BaselineWeight**and**InterventionWeight**. Using the Analysis menu in SPSS, go to Compare Means, Go to the Paired Sample*t*-test. Add the**BaselineWeight**and**InterventionWeight**in the Pair 1 fields. Click OK. Report the mean weights, standard deviations,*t-statistic,*degrees of freedom, and p level. Report as*t(df)=value, p = value.*Report the*p*level out three digits.**INDEPENDENT SAMPLE T-TEST:**Identify the variables**InterventionGroups**and**PatientWeight**. Go to the Analysis Menu, go to Compare Means, Go to Independent Samples*t*T-test. Add**InterventionGroups**to the Grouping Factor. Define the groups according to codings in the variable view (1=Intervention, 2 =Baseline). Add**PatientWeight**to the test variable field. Click OK. Report the mean weights, standard deviations,*t-statistic,*degrees of freedom, and p level. Report*t(df)=value, p = value.*Report the*p*level out three digits**CHI-SQUARE (Independent):**Identify the variables**BaselineReadmission**and**InterventionReadmission**. Go to the Analysis Menu, go to Descriptive Statistics, go to Crosstabs. Add**BaselineReadmission**to the row and**InterventionReadmission**to the column. Click the Statistics button and choose Chi-Square. Select eta to report the Effect Size. Click suppress tables. Click OK. Report the frequencies of the total events, the chi-square statistic, degrees of freedom, and*p*Report ꭓ2 (df) =value,*p*=value. Report the*p*level out three digits.**MCNEMAR (Paired):**Identify the variables**BaselineCompliance**and Go to the Analysis Menu, go to Descriptive Statistics, go to Crosstabs. Add**BaselineCompliance**to the row and**InterventionCompliance**to the column. Click the Statistics button and choose Chi-Square and McNemars. Select eta to report the Effect Size. Click suppress tables. Click OK. Report the frequencies of the events, the Chi-square, and the McNemar’s*p*level. Report (*p =*value). Report the*p*level out three digits.**MANN WHITNEY U:**Identify the variables**InterventionGroups**and Using the Analysis Menu, go to Non-parametric Statistics, go to LegacyDialogs, go to 2 Independent samples. Add I**nterventionGroups**to the Grouping Variable and**PatientSatisfaction**to the Test Variable. Check Mann Whitney U. Click OK. Report the Medians or Means, the Mann Whitney U statistic, and the*p*level. Report (*U =*value,*p =*value). Report the*p*level out three digits.**WILCOXON Z:**Identify the variables**BaselineWeight**and**InterventionWeight**. Go to the Analysis Menu, go to Non-parametric Statistics, go to LegacyDialogs, go to 2 Related samples. Add the**BaselineWeight**and**InterventionWeight**in the Pair 1 fields. Click OK. Report the Mean or Median weights, standard deviations, Z*-statistic,*and*p*Report as (Z*=*value,*p =*value). Report the*p*level out three digits.

Include the following in your paper:

- Discussion of the types of statistical tests used and why they have been chosen.
- Discussion of the differences between parametric and non-parametric tests.
- Description of the reported results of the statistical tests above.
- Summary of the conclusive result of the data analyses.
- Outputs from the statistical analysis provided as an Appendix to the paper.
- Comparison table of the variable’s level of measurement provided as an Appendix to the paper.

Use the following guidelines to report the test results:

**Statistically Significant Difference:**When reporting exact p values, state early in the data analysis and results section, the alpha level used for the significance criterion for all tests in the project.An alpha or significance level of < .05 was used for all statistical tests in the project. Then if the*Example:**p-*level is less than this value identified, the result is considered statistically significant. A statistically significant difference was noted between the scores before compared to after the intervention*t*(24) = 2.37,*p*= .007.**Marginally Significant Difference:**If the results are found in the predicted direction but are not statistically significant, indicate that results were*marginally*Scores indicated a marginally significant preference for the intervention group (*Example:**M*= 3.54,*SD*= 1.20) compared to the baseline (*M*= 3.10,*SD*= .90),*t*(24) = 1.37,*p*= .07. Or there was a marginal difference in readmissions before (15) compared to after (10) the intervention ꭓ2(1) = 4.75,*p*= .06.**Non-Significant Trend:**If the*p*-value is over .10, report results revealed a non-significant trend in the predicted direction.Results indicated a non-significant trend for the intervention group (14) over the baseline (12), ꭓ2(1) = 1.75,*Example:**p*= .26.

The results of the inferential analysis are used for decision-making and not hypothesis testing. It is important to look at the real results and establish what criterion is necessary for further implementation of the project’s findings. These conclusions are a start.

**Portfolio Practice Hours:**

Practice immersion assignments are based on your current course objectives and is application-based learning using your real-world practice setting. These assignments earn practice immersion hours and are indicated in the syllabus by a Portfolio Practice Hours statement, which reminds you, the learner, to enter in a corresponding case log in Typhon. Actual practice immersion hours are entered, but the average hours associated with each practice immersion assignment is 10.

You are required to complete your assignment using a real-world application. Real-world application requires the use of evidence-based data, contemporary theories, and concepts presented in the course. The culmination of your assignment must present a viable application in a current practice setting. For more information on parameters for practice immersion hours, please refer to DNP resources in the DC Network.

To earn portfolio practice hours, enter the following after the references section of your paper:

*Practice Hours Completion Statement DNP-830*

*I, (INSERT NAME), verify that I have completed (NUMBER OF) practice immersion hours in association with the goals and objectives for this assignment. I have also tracked said practice immersion hours in the Typhon Student Tracking System for verification purposes and will be sure that all approvals are in place from my faculty and practice mentor.*
