Introduction to statistics- Sample size (one observation → n=1)
- Comparison (control group, for example no treatment group or placebo)
- Confounding factor (factor that has an influence on the outcome of the experiment)
- Sampling should be representative for the whole population.
- Ethics
- Blinding (not knowing which organisms get which treatment, organisms not knowing
that they get treatment)

Random samples: means that every subject in the population has the same chance of being
selected in the sample.
