What is the purpose of introducing replication in a study?
What is the purpose of introducing replication in a study?
- To introduce variability and complexity into the study design
- To conduct the experiment without any control or planning
- To increase the precision of a study and estimate main effects and interactions accurately (correct)
- To decrease the accuracy of the main effects and interactions
What does the Principle of Randomization protect against in an experiment?
What does the Principle of Randomization protect against in an experiment?
- It protects against deliberate manipulation of extraneous factors
- It protects against the chance variation caused by extraneous factors (correct)
- It protects against the effects of extraneous factors by introducing variability
- It protects against the accurate estimation of main effects and interactions
What does the Principle of Local Control emphasize in experimental designs?
What does the Principle of Local Control emphasize in experimental designs?
- Dividing the field into several homogeneous parts known as 'blocks' (correct)
- Measuring the contribution of treatments to the total variability of the data
- Deliberately introducing variability caused by extraneous factors
- Eliminating all sources of variability from the experimental error
