- What is an experiment?You are concerned that nausea may be a side effect of Tamiflu, but you cannot just give Tamiflu to patients with the flu and say that nausea is a side effect if people become nauseous. This is because nausea is common for people who have the flu. From past studies you know that about 31% of people who get the flu experience nausea. You collected data on 2211 patients who were taking Tamiflu to relieve symtoms of the flu, and found that 741 experienced nausea.
