PSY 870: Module 5 Problem Set
Anxiety and Country
This study examined differences in anxiety level between an industrial country and a
nonindustrial country. Anxiety is assessed three ways—cognitive, affective, and behavioral—
with higher scores indicating higher levels of the anxiety dimensions.
Directions:
Using the SPSS data file for Module 5 (located in Topic Materials), answer the following
questions. NOTE: Helpful hints are provided here for you to use while answering these
questions.
1. What is the ONE independent variable in this study? What are the dependent variables?
2. Why is a one-way between-subjects MANOVA appropriate to use for this research
design?
HINT:
Consider the number of IVs and the number of DVs for your answer.
3. Did you find any errors that the researcher made when setting up the SPSS data file
(don’t forget to check the variable view)? If so, what did you find? How did you correct
it?
HINT:
YES! The Measures (for scale of measurement) is wrong for each of the 4 variables!
You need to indicate what was wrong and what should be the correct measures.
4. Perform Initial Data Screening. What did you find regarding missing values, univariate
outliers, multivariate outliers, normality? Although you are not asked to make
adjustments, what should you consider when you find these kinds of outcomes?
HINTS:
For missing values, see Case Processing Summary
Univariate outliers: inspect boxplots
Multivariate outliers: Don’t forget to create the Case ID variable to do this
analysis. Then, perform a regression analysis with CaseID as the DV and
Country as the IV in order to compute the Mahalanobis distance measures. Be
sure to click Save when you are setting up the regression so the regression scores
