  • For this assessment, you will complete an SPSS data analysis report using a one-way ANOVA for assigned variables.
    We are often confronted with a need to compare the means of more than two groups. We may also need to compare more than two scores among a sample of participants. ANOVA, ANalysis OVAariance, is a technique designed to address such questions.
    SHOW LESSBy successfully completing this assessment, you will demonstrate your proficiency in the following course competencies and assessment criteria:
    • Competency 1: Analyze the computation, application, strengths, and limitations of various statistical tests.
      • Develop a conclusion, including strengths and limitations of a one-way ANOVA.
    • Competency 2: Analyze the decision-making process of data analysis.
      • Analyze the assumptions of a one-way ANOVA.
    • Competency 3: Apply knowledge of hypothesis testing.
      • Articulate a research question, null hypothesis, alternative hypothesis, and alpha level.
    • Competency 4: Interpret the results of statistical analyses.
      • Interpret the one-way ANOVA output.
    • Competency 5: Apply a statistical program's procedure to data.
      • Apply the appropriate SPSS procedures to check assumptions and calculate the one-way ANOVA to generate relevant output.
    • Competency 6: Apply the results of statistical analyses (your own or others) to your field of interest or career.
      • Develop a context for the data set, including a definition of required variables and scales of measurement.
    • Competency 7: Communicate in a manner that is scholarly, professional, and consistent with the expectations for members in the identified field of study.

    SHOW LESSApplication of F-Tests
    • Is there a research question from your professional life or career specialization that can be addressed by a one-way ANOVA?
    • Why would a one-way ANOVA be the appropriate analysis for this research question?
    • What is the expected outcome?
