Q: What are the similarities between descriptive and inferential statistics? What are the differences? When should you use descriptive and inferential statistics? Give two specific examples of descriptive statistics and two specific examples of inferential statistics.

o Define the following terms and describe the relationship between them: single-case research design, small-N research design, single-subject design, case study. When should each be used?
o What are true experiments? How are threats to internal validity controlled by true experiments? How are true experiments different from quasi-experiments?
o What are pseudo or quasi-experimental designs? Why are they important? When would we use a quasi-experiment? Provide a specific example of when a quasi-experiment should be used instead of a true experiment.
o What is a correlation and how is it different from a true experiment and a pseudo or quasi-experiment?
