1:  Which of the following is not an example of a descriptive research design?
A: Case study
B: Cross-sectional study
C: Correlational study
D: Factor analytic study

2:  Which of the following is a limitation of survey studies?
A: They are costly to administer.
B: They can contain a large amount of researcher bias.
C: They cannot be administered to large samples.
D: They cannot probe deeply into the complexities of human behavior.

3:  A researcher collects data using a reliable and valid instrument with a sample of subjects at one time point. This is an example of:
A: A cross-sectional study
B: A psychometric study
C: A single subject study
D: A trend study

4:  Which of the following is a strength of a cross-sectional study?
A: There are no loss of subjects due to attrition.
B: Making causal associations are relatively easy.
C: The findings can capture changes that occur over time.
D: They are very practical for studying rare diseases.

5:  Which type of design is most powerful in assessing the consequences of certain health behaviors?
A: Cross-sectional
B: Longitudinal
C: Correlational
D: Epidemiologic

6:  How are case studies different from single-subject studies?
A: A case study is an experiment with a sample of one, while a single subject study involves qualitative methods with one subject.
B: A case study can involve up to 10 subjects, while a single-subject study involves only one subject.
C: A case study is a detailed description of a single case, while a single-subject study is an experiment with one subject..
D: A case study uses quantitative measures, while a single-subject study uses qualitative measures.

7:  What limitation is common to both case studies and single-subject studies?
A: The effects of an intervention cannot be determined.
B: The measurement of variables lack reliability.
C: The results cannot be generalized to larger populations.
D: The researcher introduces bias.

8:  Which of the following types of studies does not examine the relationship between two variables?
A: Correlational
B: Tests of spurious relationship
C: Prediction
D: Tests of model fit

9:  Which of the following statements best describes a spurious relationship?
A: One variable moderates the effect of the independent variable on the dependent variable
B: Two variables are not correlated until a third variable is added into the correlation.
C: One variable mediates the effect of the independent variable on the dependent variable
D: Two variables are statistically correlated, but the correlation is in fact invalid.

10:  Which statement best describes the purpose of model-testing designs in research?
A: They quantify the relationship of a predictor variable and an outcome variable.
B: They test for a relationship between a spurious variable and a second variable.
C: They quantify the accuracy of relationships and interrelationships of a set of variables.
D: They test for the effect size of a treatment in an experiment study.
