Can you help w/ interpret SPSS output? (Regression Assumptions)
- Annual income (in thousands
of dollars) - Average number of hours
spent exercising per week - Years of education (range is
0 – 10, please refer to the values entered in the data file) - Average number of hours
spent volunteering per month
The basic questions I want you to answer (based on this fictional data
set) are, “Do these variables predict annual income” and “How valid is the
regression model?”
Assumptions
Comment on the reasonableness of each of the following assumptions. In your comments, please include the values
from your output and the criteria for making your determination
1. Residuals
2. Normality of errors
3. Homoscedasticity and
independence of errors
4. Multicollinearity
Reasonableness
of the Model
5. Which values should you examine
in the ANOVA table in your output? What
do these values indicate, or what would you conclude, for this data set?
6. What do the values of R square
and Adjusted R square indicate about this model?
