Why This Matters for Nursing: Nursing is evidence-based. Understanding how studies are designed, why controls matter, and how to interpret results helps you evaluate treatments and apply research to patient care.
The scientific method is a systematic approach to understanding the world through observation, hypothesis, experimentation, and analysis.
| Step | What It Is | Example |
|---|---|---|
| 1. Observation | Notice something interesting | "Patients in Room A heal faster" |
| 2. Question | Ask why | "Does natural light affect healing?" |
| 3. Hypothesis | Propose an answer | "Patients exposed to natural light heal faster" |
| 4. Experiment | Test the hypothesis | Compare healing in lit vs. dark rooms |
| 5. Data Collection | Gather results | Record healing times |
| 6. Analysis | Interpret data | Calculate averages, compare groups |
| 7. Conclusion | Accept or reject hypothesis | "Data supports the hypothesis" |
| 8. Communication | Share findings | Publish in a journal |
