DATA SETS:
BPA Concentration by Age Class
BPA Concetration by Gender
BPA Concentration by Ethnic Group
All data come from the Centers for Disease Control, Fourth National Report on Human Exposure to Environmental Chamicals, February 2015.
Studies of BPA in urine of human test subjects indicate nearly universal presence, suggesting that exposure is widespread. In this exercise, we will look at the mean concentrations measured in micrograms/liter. We will begin by examining the data for all the years available (in two-year increments) by age group. To do so, select “BPA Concentration by Age Class” from the drop-down menu.
