1. What is an experimental field study?
2. What is a quasi-experiment? How may it differ from a true experiment?
3. What are the types of experimental designs commonly used in the field?
4. What is a one-group pre-test-post-test design?
5. Explain why a one-group pre-test-post-test design is an uninterpretable design.
6. What is a randomised pre-test-post-test experimental/control groups design?
7. What is the non-equivalent version and how does it differ from a true experiment?
8. Explain why a non-equivalent pre-test-post-test control group design is an interpretable (quasi-) experimental design.
9. What variations can be made to improve the non-equivalent pre-test-post-test control group design?
