EDD611 Inquiry I Lab 5
Lab 5 focuses on conducting a multiple regression utilizing 10-15 independent variables grounded in Astin's I-E-O model.
By the end of Lab 5, students will be able to:
- Conduct a multiple regression analysis
- Apply Astin's I-E-O model to multiple regression analysis
- Run a descritves to determine usability of variables
Before starting your exercises, ensure that your SPSS is open.
For instructions on how to download and/or open the SPSS software, please see the following guide: EDD611 Inquiry I Getting Started
It is strongly recommended to run a descriptive analysis of the variables you plan to use.
This will allow you to verify that the selected variables have data.

Astin, A.W. (2012). Assessment for excellence: The philosophy and practice of assessment and evaluation in higher education. Rowman & Littlefield Publishers.
This multiple regression lab is based on the following research question:
What is the relationship with student background characteristics, college experiences, and (your chosen variable)?
Example: What is the relationship with student background characteristics, college experiences, and Sense of Belonging?
Step 1:
Click on Analyze, Regression, then Linear
Step 2:
Select the dependent (outcome) variable of your choice
Example: CSS Sense of Belong Score [SENSE_BELONG]
Step 3:
Click on the top arrow button to add it to the Dependent field
Step 4:
Select the (input) variable of your choice
Example: Your sex: [SEX]
Step 5:
Click on the (second from top) arrow to add it to the Independent(s) field in Block 1 of 1
Step 6:
Click on the Next button to move to Block 2
The block will update to show 'Block 2 of 2'
Step 7:
Select the (environment) variable(s) of your choice
Step 8:
Click on the (second from top) arrow to add it to the Block 2 of 2 field
See the Descriptives section for instructions on how to run a descriptive analysis
Step 9:
Repeat Steps 7 and 8 to add the additional (environment) variables of your choice:
Example:
- Satisfaction: Academic advising [SATIS01]
- Act: Discussed course content with students outside of class[ACT14]
- Act: Felt isolated from campus life [ACT23]
- Act: Studied with other students [ACT55]
Step 10:
When you ahev added all of your variables, click on the Statistics button
Step 11:
Ensure the following checkboxes are checked:
Model fit
R squared change
Descriptives
Collinearity diagnostics

Step 13:
Click the Continue button

Step 14:
Click the OK button
The results will populate in your Output window
If encounter the following error, you most likely included a variable with valid, complete, and usable information.

It is recommended to select other variables and run a descriptive analysis to ensure there is usable data for that variable.
See the Descriptives section for more information
A descriptive analysis allow you to confirm that the variables you intend to use contain valid information.
Step 1:
Click Analyze, Descriptive Statistics, then Descriptives
Step 2:
Select the variable(s) you would like to check for data
Step 3:
Click on the arrow button to move the variable to the Variable(s) field
Step 4:
When you have added all the variables you would like to check, click the OK button
Step 5:
In your Output window, review the output for any field with a zero
Any field with a '0' indicates that there is no data for that variable.
You may want to change variables or just eliminate the variables with no data.
Write up your multiple regression analysis, making sure to include the following elements:
- Research question, noting your final variable
- Dependent variable (Outcome)
- Block 1 variables (Inputs)
- Block 2 variables (Environment)
Example:
You are welcome to use some of the variables, but please avoid using duplicating this example set.
