One Way Anovas As with your previous assignments, you will complete this with the DAA Template. Links to additional resources are available in the Resources area.

Reminder: The format of this SPSS assignment should be narrative with supporting statistical output (table and graphs) integrated into the narrative in the appropriate place (not all at the end of the document).

You will analyze the following variables in the grades.sav data set: section, quiz3.

Step 1: Write Section 1 of the DAA Provide a context of the grades.sav data set. Include a definition of the specified variables (predictor, outcome) and corresponding scales of measurement. Specify the sample size of the data set.

Step 2: Write Section 2 of the DAA Analyze the assumptions of the one-way ANOVA. Paste the SPSS histogram output for quiz3 and discuss your visual interpretations. Paste SPSS descriptives output showing skewness and kurtosis values for quiz3 and interpret them. Paste SPSS output for the Shapiro-Wilk test of quiz3 and interpret it. Report the results of the Levene test and interpret it. Summarize whether or not the assumptions of the one-way ANOVA are met.

Step 3: Write Section 3 of the DAA Specify a research question related to the one-way ANOVA. Articulate the null hypothesis and alternative hypothesis. Specify the alpha level.

Step 4: Write Section 4 of the DAA Begin by pasting SPSS output of the means plot and providing an interpretation. Also report the means and standard deviations of quiz3 for each level of section.

Next, paste the SPSS ANOVA output and report the results of the F test, including: Degrees of freedom. F value. p value. 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.

Step 5: Write Section 5 of the DAA Discuss the conclusions of the one-way ANOVA as it relates to the research question. Conclude with an analysis of the strengths and limitations of one-way ANOVA.

Please let me know if there is anything else you need for this.

DAA 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 DAA. Remove this text and provide a brief introduction.

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).

Testing Assumptions

1. Articulate the assumptions of the statistical test.

2. Paste SPSS output that tests those assumptions and interpret them. Properly embed 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.

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.

Interpretation

1. Paste SPSS output for an inferential statistic and report it. Properly embed SPSS output where appropriate. Do not string all output together at the beginning of the section.

2. Interpret statistical results against the null hypothesis.
Conclusion

1. State your conclusions.

2. Analyze strengths and limitations of the statistical test.
