“This week, you will apply your understanding of correlation to the SPSS
data set.
CORRELATION APPLICATION AND INTERPRETATION
Instructions
Complete the following for this assignment:
For this assignment, you will use the Data Analysis and Application
template (DAA Template [DOC]).
For help with SPSS, refer to IBM SPSS Step-by-Step Guide:
Correlations [DOC].
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.
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.
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.”
