In this module you will have the opportunity to explore the frequency of different types of residential moves carried out by Americans. You will examine some of the basic determinants of residential mobility by looking at variations in different types of mobility by age, marital status, education, and housing tenure. Finally, you will have an opportunity to test hypotheses, drawn from a popular theoretical perspective, about racial differences in residential mobility.

This resource discusses sample sizes and how they are chosen.

This dataset comes from a study of 8 healthy males randomly assigned to a two-period crossover design, in which they either fasted and then ate, or ate and then fasted. They were given one dose of a drug, blood samples were collected and data on plasma levels were collected. Questions from this study refer to the absorption of the drug. A text file version of the data is found in the relation link.

This dataset comes from a study of 7 healthy males given a topical medication. Blood samples were collected at specified time intervals, and data on isomer concentrations were collected. Questions from this study refer to the relationship between time and concentration of the isomer. A text file version of the data is found in the relation link.

This dataset comes from a study on dogs 4 doses of a drug. Data on the alkaline phosphatase levels in their blood was collected throughout the experiment. Questions from this study refer to the relationship between dosage of the drug and alkaline blood levels. A text file version of the data is found in the relation link.
