a)identify the question, population, and sample
b)discuss any potential bias or lurking variable that may affect the results
c) write about the extent to which you can generalize the findings to all people who use cell phones
stewart fist reported the results of an experiment investigating the link between cell phone use and tumors in mice. the study exposed 100 mice to cell phone radiation for 2 1/2 hour periods each day for 18 months. the researchers fitted another 100 mice with the same type of antennas, which never had the power turned on. the tumor rate was twice as high in the exposed group vs. the unexposed group.
