Hello, i need to analyze an could you me?
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.
i know the question, population and sample, but i am having trouble identifying potential bias or finding lurking variables. this experiment looks pretty clean to me.
you, scarlett
