State your research question, null, and alternate hypothesis.
Specify the variables used in this analysis (predictor, outcome) and the scale of measurement of each variable.
State the sample size (N) and the alpha level you will use (.05 unless otherwise specified).
Explain why the analysis is a good choice based on the nature of your variables.
Step 2: Write Section 2 of the DAA: Testing Assumptions.
Articulate and test the assumptions of ANOVA.
Paste the SPSS histogram output for quiz3 and discuss your visual interpretations.

Paste the SPSS descriptives output showing skewness and kurtosis values for quiz3 and interpret them.
Paste the SPSS output for the Shapiro-Wilk test of quiz3 and interpret it.
Report the results of the Levene test and interpret it.
Explain whether the assumptions of ANOVA are met. If assumptions are not met, discuss how to ameliorate violations of the assumptions.
Step 3: Write Section 3 of the DAA: Results and Interpretation.
Paste the SPSS output of the means plot and provide an interpretation.
Also report the means and standard deviations of quiz3 for each level of the section variable.
Paste the SPSS ANOVA output and report the results of the F test. Include the following
Degrees of freedom.
Calculated effect size.
Interpretation of the effect size.
Finally, if the omnibus F is significant, provide the SPSS post-hoc (Tukey HSD) output.
Interpret the post-hoc tests.
Interpret statistical results against the null hypothesis and state whether it is accepted or rejected.
Step 4: Write Section 4 of the DAA: Statistical Conclusions.
Provide a brief summary of your analysis and the conclusions drawn.
Analyze the limitations of the statistical test.
Provide any possible alternate explanations for the findings and potential areas for future exploration.
Step 5: Write Section 5 of the DAA: Application.
Analyze how you might use this statistical approach in your field and what the potential implications would be.
Submit your DAA template as an attached Word document in the assignment area.

Nurses play vital roles in educating patients about HIV, providing support for treatment adherence, and assisting with navigation of care delivery. APRNs, further, are positioned to provide ART directly, consistent with their state practice authority.The community health nurse has professional technical skills and knowledge that the community populace may not have; thus, the nurse has the role in ensuring the quality of community-based care(Stover et al., 2021). They form a significant component in delivering quality HIV services, including counseling, adherence support, development of a referral framework, and dissemination of information. They also have the role of reporting and HIV data collection.
Demographics are essential since they offer an exhaustive comprehension of a population’s various features. The provided information is particularly vital to government organizations and institutions for making crucial policy decisions concerning the people(Stover et al., 2021). Similarly, demographics data is critical as it gives the health authorities andpopulace information they need to strategies and implements future investments and services; data from sources such as the CDC and the US Census aids in determining where assistance programs need to be directed (UNAIDS, 2021)
Step 4. Copy the ANOVA output, paste it into Section 4, and interpret it.

Step 5. Finally, if the overall ANOVA is significant, copy the post hoc output, paste it into Section 4, and interpret it.

Data Set Instructions
The grades.sav file is a sample SPSS data set. The fictional data represent a teacher’s recording of student demographics and performance on quizzes and a final exam across three sections of the course. Each section consists of about 35 students (N = 105).
Last week, you converted grades2.dat to grades.sav. There are 21 variables in grades.sav. Open your grades.sav file and go to the Variable View tab. Make sure you have the following values and scales of measurement assigned.

Data Analysis & Application Template
Data Analysis and Application (DAA) Template
Use this file for all assignments that require the DAA Template. Although the statistical tests will change from week to week, the basic organization and structure of the DAA remains the same. Update the title of the template and the running head. All should be written in narrative form (delete numbered lists).
Data Analysis Plan (1 Paragraph)
1. Briefly describe the goal of your analysis.
2. State your research question, null and alternate hypothesis.
3. Specify the independent and dependent variables used in this analysis and the scale of measurement of each variable.

5. Explain why the analysis is a good choice based on the nature of your variables.
Testing Assumptions (1-2 Paragraphs)
1. Articulate the assumptions of the statistical test.
2. Paste the SPSS output from analyses that test those assumptions and interpret them. Each pasted SPSS table or figure should be accompanied by an interpretation (that is, immediately above or below) where the output appears.
3. Summarize whether or not the assumptions are met. If assumptions are not met, discuss how to ameliorate violations of the assumptions.
Results & Interpretation (1-2 paragraphs)
1. Paste the SPSS output from you main inferential statistic(s). Each pasted SPSS table or figure should be accompanied by a statement summarizing the main finding in text form and an interpretation of that result. Be sure to include effect sizes.
2. Interpret statistical results against the null hypothesis and state whether it is accepted or rejected.
Statistical Conclusions (1 paragraph)
1. Provide a brief summary of your analysis and the conclusions drawn.
2. Analyze the limitations of the statistical test.
3. Provide any possible alternate explanations for the findings and potential areas for future exploration.
