One-Way Analysis of Variance with SPSS

As you work through this SPSS exercise, consider the application of the one-way ANOVA test to your research topic. Is it an appropriate test for your research?

To prepare for this Application:

• Review Lessons 25 and 27 in the course text Using SPSS for Windows and Macintosh: Analyzing and Understanding Data.
• Review the video program for this week, located in the Learning Resources.
• Read the ANOVA/MANOVA section of the StatSoft Electronic Textbook at http://www.statsoft.com/textbook/.
• Access the gss04student_corrected dataset in the Course Information area of the classroom to use for this Application

The assignment:

• Craft up to a one page double-spaced write up of the statistical results (include any additional pages needed for any APA tables or graphs and the SPSS syntax and output) in which you do the following:
• • State the statistical assumptions of this test.
  • Select an independent variable with three or more levels and a dependent variable.
  • Develop the null hypothesis and the alternative hypothesis for main effects.
  • Using SPSS, calculate an ANOVA. Include a post hoc test.
  • Report on the p value and the confidence interval.
  • Interpret the confidence interval.
  • Decide whether to reject or retain the null hypothesis based on main effects and/or post-hoc statistical tests.
  • Generate syntax and output files in SPSS. You will need to copy and paste these into your Application document.
  • Based on your SPSS analysis, report the results using correct APA format. Include results for post hoc tests where appropriate. Your report should include the following:
  • • SPSS syntax and output files
    • ANOVA table
