Study Notes
Science and the Scientific Method
- Science is defined as knowledge gained through study or practice.
- Research is the systematic study to discover or establish facts and principles.
- EMS is a blend of science (knowledge) and art (application).
- The scientific method is a process for constructing an accurate representation of the world, requiring reliability, consistency, and non-arbitrariness.
Steps of the Scientific Method
- Observe and Ask Questions: Identify a phenomenon and pose a question about it. An example is observing more psychiatric calls during full moons.
- Conduct Research: Gather background information through resources like the internet, scientific databases (like PubMed). Examine existing studies on a similar topic.
- Construct a Hypothesis: Formulate a specific, measurable question that addresses the initial observation. Example: "Psychiatric emergencies are more common during full moon phases."
- Test the Hypothesis by Experimentation: Design a controlled experiment to test the hypothesis. Key to this step is defining variables (in the example: psychiatric call definition, full moon definition, time frame for study).
- Analyze Results and Draw Conclusions: Statistical analysis of data determines if the hypothesis is supported or refuted.
- Revise the Hypothesis: If results don't support the hypothesis, revise it to reflect the findings. If results support the hypothesis, consider refining a variable or running the experiment again.
- Report Results: Share findings, even if the initial hypothesis was proven false, in peer-reviewed journals. This facilitates scientific discussion and further research.
Iterative Process
- The scientific method is iterative; the process may require revisiting steps as new information becomes available.
