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 week’s assignment 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. Social Science homework help
Step 2: Write Section 2 of the DAA: 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.
- 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
- Paste 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 results.
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 or practice. Social Science homework help
