types of experimental research

Experimental research can be categorized into several types: 1. **Laboratory Experiments**: Conducted in controlled environments to isolate variables. 2. **Field Experiments**: Carried out in real-world settings, providing more natural results. 3. **Clinical Trials**: Test new treatments or drugs on human participants to assess effectiveness and safety. 4. **Quasi-Experiments**: Similar to experiments but lack random assignment, often used in social settings to study effects of interventions. Each type aims to establish cause-and-effect relationships by manipulating one variable and observing changes in another, helping researchers understand how different factors influence outcomes.
