Description

  • One-Way ANOVA

    Resources

    As with your previous assignments, you will complete this assignment 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 text in the appropriate places (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 the 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 the section variable.
    • 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.
    Submit your DAA Template as an attached Word document in the assignment area.

    [u10d1] Unit 10 Discussion 1

    Course Reflection

    Resources

    For this discussion, address the following:
    • Reflect on your experiences upon completing this course.
    • Evaluate your current level of statistics anxiety relative to your initial level in Unit 1 of the course.
    • Describe how your view of statistics has changed from the beginning of the course.
    • Discuss how you can use statistics in your career. Do you have a different perception than you initially did? Justify your answer.

    Response Guidelines

    Provide a substantive contribution that advances the discussion in a meaningful way by identifying strengths of the posting, challenging assumptions, and asking clarifying questions. Your response is expected to reference the assigned readings, as well as other theoretical, empirical, or professional literature to support your views and writings. Reference your sources using standard APA guidelines. Review the Participation Guidelines section of the Discussion Participation Scoring Guide to gain an understanding of what is required in a substantive response.
    • PSY learners, you are required to respond to at least two of your peers' posts.
    • Learners from all other programs, you are required to respond to at least one of your peers' posts.

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. 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. Analyze strengths and limitations of the statistical test. 3 DATA ANALYSIS AND APPLICATION TEMPLATE References Provide references if necessary. 4 IBM SPSS Step-by-Step Guide: One-Way ANOVA Note: This guide is an example of creating ANOVA output in SPSS with the grades.sav file. The variables shown in this guide do not correspond with the actual variables assigned in Unit 10 Assignment 1. 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 Unit 10 Assignment 1, 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 Unit 10 assignment 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: • 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 Homogeneity 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.
