Types of Research

Research can be quantitative, qualitative, or mixed.
Quantitative research uses numbers to describe phenomena objectively.
Qualitative research uses words to describe phenomena subjectively.
Mixed research combines both quantitative and qualitative approaches.
Most medical research is quantitative.

Quantitative Research

Objective and specific.
Aims to determine relationships between variables.
Independent variable affects the dependent variable.
Dependent variable is affected by the independent variable.
Example: EMS response time (independent) and patient survival (dependent).
Types:
- Experimental: Manipulates independent variables.
- Nonexperimental: Observes naturally occurring variables (e.g., psychiatric patients and the full moon).
- Survey: Collects data from a population through questionnaires or interviews.

Qualitative Research

Focuses on the "why" of phenomena, not the "how."
Primarily uses qualitative (non-numeric) data.
Often conducted in natural settings.
Example: Studies on EMS worker stress.
Applications: Quality assurance, customer surveys.

Research Designs

Retrospective studies: Analyze existing data.
- Advantages: Data readily available, less expensive.
- Disadvantages: Potential for bias, less accurate.
Prospective studies: Collect data over time.
- Advantages: More objective, accurate, and complete than retrospective.
- Disadvantages: More expensive than retrospective.
