You will analyze the following variables in the grades.sav data set:

• gender
• gpa
• total
• final

Step 1: Write Section 1 of the DAA.

• Provide the context of the grades.sav data set.
• Include a definition of the specified variables and corresponding scales of measurement.
• Indicate the type of correlation for each X, Y pair (Pearson's r, Spearman's r, point-biserial r, et cetera).
• Specify the sample size of the data set.

Step 2: Write Section 2 of the DAA.

• Test the assumptions of correlation for gpa and final.
• Paste the SPSS histogram output for each variable and discuss your visual interpretations.
• Paste SPSS descriptives output showing skewness and kurtosis values and interpret them.
• Paste SPSS scatter plot output with "gpa" set to the horizontal axis and "final" set to the vertical axis. Conduct a visual inspection of the scatter plot to analyze other assumptions of correlation.
• Summarize whether or not the assumptions of correlation are met.

Step 3: Write Section 3 of the DAA.

• Specify a research question related to gpa and final.
• Articulate the null hypothesis and alternative hypothesis.
• Specify your alpha level.

Step 4: Write Section 4 of the DAA.

• 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.

Step 5: Write Section 5 of the DAA.

• Discuss the implications of this correlation as it relates to the research question.
• Conclude with an analysis of the strengths and limitations of correlational analysis.
