Correltation Application and Interrpretation2 Please Follow Instructions.

CORRELATION APPLICATION AND INTERPRETATION

Instructions

Complete the following for this assessment:

· For this assessment, you will use the Data Analysis and Application Template (DAA Template [DOC]).

· For help with SPSS, refer to IBM SPSS Step-By-Step Instructions: Correlations [DOCX].

· For help copying SPSS output into your DAA, review the Copy/Export Output Instructions [HTML].

· For information on the data set, you may find the Data Set Instructions [DOC] helpful.

· Refer to the 7864 Course Study Guide for information on analyses and interpretation.

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

SPSS Variable	Definition
Quiz1	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

Step 1: Write Section 1 of the DAA: The Data Analysis Plan

· 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 total and final.

· State a research question, null hypothesis, and alternate hypothesis for GPA and quiz1.

Step 2: Write Section 2 of the DAA: Testing Assumptions

· Create a descriptive statistics table in SPPS to assess normality. This table should include the four variables named above.

· Pase the table in the DAA.

· Interpret the skewness and kurtosis values and how you determined whether the assumption of normality was met or violated.

Step 3: Write Section 3 of the DAA: Results and Interpretation:

· Pase the intercorrelation matrix (SPSS Correlation table) for the four variables into the document.

· Below the output, first report the total-final correlation including degrees of freedom, correlation coefficient, and p value. Specify whether or not to reject the null hypothesis for this correlation.

· Second, report the gpa-quiz1 correlation including degrees of freedom, correlation coefficient, and p value. Specify whether or not to reject the null hypothesis for this correlation.

Step 4: Write Section 4 of the DAA – Statistical Conclusions:

· Provide a brief summary of your analysis and the conclusions drawn about correlations.

· Analyze the limitations of the statistical test and/or possible alternative explanations for your support.

Step 5: Write Section 5 of the DAA – Application:

· Analyze how you might use correlations in your field of study.

· Name two variables that would work for such an analysis and why studying the relationship may be important to the field of practice.

Submit your 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.
