Study Notes
Scientific Methodology
- When alternative explanations are disproven in science, the existence of a particular phenomenon or theory is indirectly proven.
- In experimental design, a 'stratified' approach refers to the division of the sample into subgroups or blocks based on specific characteristics, ensuring that each subgroup is representative of the population.
Experimental Design Techniques
- Random interspersion in an experiment serves to minimize any potential biases or effects of external factors, increasing the validity of the results.
- The main advantage of having replicates in an experiment is that it allows for a more accurate estimation of the true effect of the treatment, as it reduces the impact of random errors.
Experimental Details
- In the given experiment, there were [number] independent samples per treatment.
