Which study would be categorized as a replication study?
1. A study in which the researcher investigates how cells divide and grow in various environments.

3. A study looking at the ability of a new medication to control hallucinations and delusions.
4. A study measuring the effect of a new treatment for pressure ulcers.

Rationale 1: Whereas many studies have been done on cell division and growth, this option does not specifically indicate that the researcher is repeating another researcher's study.
Rationale 2: This is the best answer because the study is specifically designed to repeat the study done by another researcher. Replication studies are useful in validating findings.
Rationale 3: This is a new drug, so this is a new study, not a replication study.
Rationale 4: This is a new treatment, so this is a new study, not a replication study.
