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.
