Five Principles of Experimental Design

The five principles of experimental design are: 1. **Control**: Keep variables constant to ensure that the results are due to the factor being tested. 2. **Randomization**: Randomly assign subjects to different groups to reduce bias and ensure that results are generalizable. 3. **Replication**: Repeat experiments to confirm results and ensure they are not due to chance. 4. **Blocking**: Group similar subjects together to reduce variability and improve accuracy in results. 5. **Blinding**: Conceal information from participants or researchers to prevent bias in how the experiment is conducted or interpreted. Together, these principles enhance the reliability of experimental results.
