Each subject who suffers from hay fever and volunteers for the study is observed on three separate days, with a different treatment used each day.

i. The study can conclude that the treatment is the cause of the difference in hay fever symptoms.
ii. The results of the study can be generalized to the population of all hay fever sufferers
