Exam 2: Chapter 14 (Generalizability and Replication)

Question 1

Replication

Answer 1

Attempting to repeat the results of a research study (experiment) by repeating the original study.

Question 2

Exact Replication

Answer 2

Repeat the study under the same conditions, with as few changes as possible

• Purpose: To confirm initial findings (and confirm results were not due to a Type I Error).

Question 3

Conceptual Replication

Answer 3

Testing the same hypothesis of a study, but with different methods.

• Purpose: To test generalizability, the truth of the underlying hypothesis, and discover “boundary conditions.”
• Importance: without them, we would never know how generalizable a finding is…

Question 4

Key components of science:

Answer 4

• Based on evidence (empirical)
• Progressive
• Cumulative
• NOT free from errors
• Self-correcting → via replication

Question 5

Importance of Replication

Answer 5

Builds confidence in the truth of scientific evidence

• Generalize results (conceptual replications)
• Weed out false effects (Type I errors, and detect fraud)
