Document Summary

In a study of sickle cell anemia, 150 patents were given the drug hydroxyurea, and 150 were given a placebo. The researchers counted the episodes of pain in each subject. Level: there are 2 hydroxyurea and placebo. We want to study the absorption of a drug into the bloodstream. An injection of the drug was given to 25 people and after 30 minutes concentration of the drug in the bloodstream was determined. Identify the experimental units, factor, level and response variable. Factor: drug being injected (since there is only one factor with one level, it is also known as the treatment). Response variable: concentration of drug in bloodstream after 30 mins. A supermarket is interested in studying how the sales for their candy were doing. They tested 12 equal sized stores, each store was set up exactly the same way. There were two aisles where the candy was located. There were three shelves in these aisles (top, middle and bottom).
