Independent and Dependent Variables
Independent Variable: Dosage of lipopolysaccharide
Number of subjects per group
The subjects will be selected by going to multiple college campuses in the Phoenix area including technical schools and community colleges. The subjects will be both male and female students of equal proportions. College students are the perfect subjects for a graduate student low on cash and their health can handle the induced inflammation better than of the elderly.
Sources of Error and Bias
A potential source of error would be if the subjects already had a pre-existing inflammatory condition. This can be controlled by having each subject take a background test in order to eliminate candidates that do have such conditions from the sample. Another error may be related to the high level of health that most college students possess and their high percentage of physical activity compared to that of most elderly citizens. Furthermore, another error would be if the students that are randomly chosen drink an excessive amount of alcohol.
