Independent and Dependent Variables
The independent variable is the amount of lipopolysaccharide given to the subjects. The dependent variable is the amount of Inflammotin in each subject's bloodstream.
Number of subjects per group
Each group of eight subjects will consist of four males and four females. Within each group there will be both a male and a female in each of the following age ranges: 60-64, 65-69, 70-74, and 75-79. These subjects will be randomly selected in order to represent a variety of healths, life-styles, locations, and ethnic backgrounds.
Sources of Error and Bias
One source of bias occurred when we chose our test subjects. Our subjects' ages ranged from sixty to eighty years and left out any ages above the national average age. One possible way to control this source would be to expand the number of subjects per group to include ages ranging form eighty to one hundred years. A source of error occurred between the measurement per pill of lipopolysaccharide. Our test amounts only include even numbers bellow ten. To control this error, we could add more groups to add various other measurement between the chosen milligrams per pill. Another possible source of error could have occurred when choosing test subjects. If any of our subjects had a preexisting health condition and/or were taking any medication, these unknown variables could have an effect on their body's ability to produce Inflammotin. In order to control this source of error, we would have to screen any subjects with preexisting health conditions as well as know of any medication the subjects had or are taking.
