Assessment 2: Correlation Application and Interpretation

Assessment 2: Correlation Application and Interpretation

 

Pages: 7

  • Complete an SPSS data analysis report to analyze correlation for assigned variables.

Exploring the associations between some variables in the courseroom using correlations might provide some important information about learner success. You’ll need to pay attention to both magnitude, which is the strength of the association, and directionality, which is the direction (positive or negative) of the association. During this assessment, you’ll start learning about how to best approach correlational analyses like these and start getting some answers. You’ll explore the relationships that may or may not exist in your courseroom data.

In this assessment, you’ll get a chance to run and interpret your first inferential statistics analysis: correlations. Your readings and the Course Study Guide will help you in your efforts.

Instructions

You will complete this assessment using the Data Analysis and Application Template [DOC] (also known as the DAA Template).

The grades.sav file is a sample SPSS data set. The data represent a teacher’s recording of student demographics and performance on quizzes and a final exam across three sections of the course. Each section consists of 35 students (N = 105). There are 21 variables in grades.sav.

This assessment is on correlations. You will analyze the following variables in the grades.sav data set:

SPSS Variables and Definitions
SPSS Variable Definition
Quiz 1 Quiz 1: number of correct answers
GPA Previous grade point average
Total Total number of points earned in class
Final Final exam: number of correct answers

The DAA Template has five sections:

    • The Data Analysis Plan.
    • Testing Assumptions.
    • Results and Interpretation.
    • Statistical Conclusions.
    • Application.

Step 1: The Data Analysis Plan

In Step 1:

    • Name the four variables used in this analysis and whether they are categorical or continuous.
    • State a research question, null hypothesis, and alternate hypothesis for one X-Y pair. For example, you could articulate a research question, null hypothesis, and alternate hypothesis for quiz1 (X) and final (Y).

Step 2: Testing Assumptions

Test for one of the assumptions of correlation—normality.

    • Create a descriptive statistics table in SPSS to assess normality. This table should include the four variables named above.
    • Paste the table in the DAA Template.
    • Interpret the skewness and kurtosis values and how you determined whether the assumption of normality was met or violated.

Step 3: Results and Interpretation

In Step 3:

    • Paste the SPSS output of the intercorrelation matrix for all specified variables:
      • First, report the lowest magnitude correlation in the intercorrelation matrix, including degrees of freedom, correlation coefficient, p value, and effect size. Interpret the effect size. Specify whether or not to reject the null hypothesis for this correlation.
      • Second, report the highest magnitude correlation in the intercorrelation matrix, including degrees of freedom, correlation coefficient, p value, and effect size. Interpret the effect size. Specify whether or not to reject the null hypothesis for this correlation.
      • Third, report the correlation between GPA and final, including degrees of freedom, correlation coefficient, p value, and effect size. Interpret the effect size. Analyze the correlation in terms of the null hypothesis.
    • Interpret statistical results against the null hypothesis, and state whether it is accepted or rejected.

Step 4: Statistical Conclusions

In Step 4:

    • 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: Application

In Step 5:

    • Analyze how you might use correlations in your field of study.
    • Name an independent variable and dependent variable that would work for such an analysis and why studying it may be important to the field or practice.

Submit your completed 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.

Make sure that your SPSS software is downloaded and installed with fully activated licensing on your computer and running properly within your operating system (PC or Mac). If you need help with these steps, refer to the SPSS Installation Helper.

Competencies Measured

By successfully completing this assessment, you will demonstrate your proficiency in the course competencies through the following assessment scoring guide criteria:

    • Competency 1: Analyze the computation, application, strengths, and limitations of various statistical tests.
      • Analyze statistical assumptions.
    • Competency 2: Analyze the decision-making process of data analysis.
      • Articulate the data analysis plan.
    • Competency 3: Apply knowledge of hypothesis testing.
      • Interpret statistical results and hypotheses.
    • Competency 4: Interpret the results of statistical analyses.
      • Explain statistical conclusions, the limitations of the test, and possible alternative explanations.
    • Competency 6: Apply the results of statistical analyses (your own or others’) to your field of interest or career.
      • Analyze the potential applications of the test in the field and their implications.
    • Competency 7: Communicate in a manner that is scholarly, professional, and consistent with the expectations for members in the identified field of study.
      • Communicate in a manner that is scholarly and professional, and adheres to APA style and formatting.
  • SCORING GUIDE

Use the scoring guide to understand how your assessment will be evaluated.
