Well designed and conducted experiments use random assignments and can be replicated.
Treatments: any specific experimental conditions applied to subjects.
Control Group: a group of individuals as similar as possible to individuals receiving treatment but do not receive treatment.
Random Assignments: experimental units are randomly assigned into the different treatment and control groups.
Replication: ensures that there are enough observations to reduce the variation in the results.
