Include the following o Degrees of freedom. o F value. o p value. o Calculated effect size. o Interpretation of the effect size. o Finally, if the omnibus F is significant, provide the SPSS post-hoc (Tukey HSD) output. o 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 assessment area. • Software The following statistical analysis software is required to complete your assessments in this course: IBM SPSS Statistics Standard or Premium GradPack, version 24 or higher, for PC or Mac. You have access to the more robust IBM SPSS Statistics Premium GradPack. Please refer to the Statistical Software page on Campus for general information on SPSS software, including the most recent version made available to Capella learners.

Running head: DATA ANALYSIS AND APPLICATION TEMPLATE Data Analysis and Application (DAA) Template Learner Name Capella University 1 DATA ANALYSIS AND 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. Discussion: Application and Interpretation Remove this text and provide a brief introduction. Section 1: Data File Description 1. Describe the context of the data set. You may cite your previous description if the same data set is used from a previous assignment. 2. Specify the variables used in this DAA and the scale of measurement of each variable. 3. Specify sample size (N). Section 2: Testing Assumptions 1. Articulate the assumptions of the statistical test. 2. Paste SPSS output that tests those assumptions and interpret them. Properly integrate SPSS output where appropriate. Do not string all output together at the beginning of the section. 3. Summarize whether or not the assumptions are met. If assumptions are not met, discuss how to ameliorate violations of the assumptions. Section 3: Research Question, Hypotheses, and Alpha Level 1. Articulate a research question relevant to the statistical test. 2. Articulate the null hypothesis and alternative hypothesis. 3. Specify the alpha level. Section 4: Interpretation 1. Paste SPSS output for an inferential statistic. Properly integrate SPSS output where appropriate. Do not string all output together at the beginning of the section. 2. Report the test statistics. 2 DATA ANALYSIS AND APPLICATION TEMPLATE 3. Interpret statistical results against the null hypothesis. Section 5: Conclusion 1. State your conclusions. 2.

The variables shown in this guide do not correspond with the actual variables assigned in Assessment 4. Carefully follow the instructions in the assignment for a list of assigned variables. Screen shots were created with SPSS 21.0. Creating One-Way ANOVA Output To complete Section 2 of the DAA for Assessment 4, you will generate SPSS output for a histogram, descriptive statistics, and the Shapiro-Wilk test, which are covered in previous step-by-step guides. The Levene test (homogeneity of variance) is covered in the steps below. Refer to the Assessment 4 instructions for a list of assigned variables. The example variables year and final are shown below. Step 1. Open grades.sav in SPSS. 1 Step 2. On the Analyze menu, point to Compare Means and click One-Way ANOVA… Step 3. In the One-Way ANOVA dialog box: •Discussion: Application and Interpretation Move the assigned dependent variable into the Dependent List box. • Move the assigned independent variable into the Factor box. The examples of final and year are shown below. • Click the Options button. 2 Step 4. In the One-Way ANOVA: Options dialog box: • Select Homogeneity of variance test (for the Levene test for Section 2 of the DAA). • Select Descriptive and Means Plot (for Section 4 of the DAA). • Click Continue. • Return to the One-Way ANOVA dialog box and select the Post Hoc button. Step 5. In the One-Way ANOVA: Post Hoc Multiple Comparisons dialog box: • Check the Tukey option for multiple comparisons. • Click Continue and OK. 3 Interpreting One-Way ANOVA Output A string of ANOVA output will appear in SPSS. (The output below is for the example variable final.) Step 1. Copy the Levene test output from SPSS and paste it into Section 2 of the DAA Template. Then interpret it for the homogeneity of variance assumption. Test of Hom ogeneity of Variances final Levene Statistic .866 df1 df2 3 Sig. 101 .462 Step 2. Copy the means plot, paste it into Section 4 of the DAA Template, and interpret it. Step 3. Copy the descriptives output. Paste it into Section 4 along with the report of means and standard deviations of the dependent variable at each level of the independent variable. Descriptives final N Mean Std. Deviation Std.
