Independent and Dependent Variables

The independent variable would be lipopolysaccharide because it is the variable being manipulated in the experiment. The Inflammatin is the dependent variable because its amount depends on how much lipopolysaccaride is in the system.

Experimental Design

10 Groups Group 1: 1 mg of Lipopolysaccharide
Group 2: 2 mg of Lipopolysaccharide
Group 3: 3 mg of Lipopolysaccharide
Group 4: 4 mg of Lipopolysaccharide
Group 5: 5 mg of Lipopolysaccharide
Group 6: 6 mg of Lipopolysaccharide
Group 7: 7 mg of Lipopolysaccharide
Group 8: 8 mg of Lipopolysaccharide
Group 9: 9 mg of Lipopolysaccharide
Group 10: 10mg of Lipopolysaccharide
-Group 10 is the controlled group because there is previous data to compare to for the use of Lipopolysaccharide to reduce the amount of Inflammatin in the body.


The subjects will be 65 years of age and older.

Number of subjects per group

Each group will contain 100 test subjects, keeping the experiment large enough to yield beneficial results, but small enough to fit the low budget.

Subject Selection

The subjects will be chosen randomly. The subjects will be of various ethnic races with different backgrounds. Although half will be males and the other half females.

Sources of Error and Bias

Sources of error and bias could truly alter the results of this experiment. Genetic and racial backgrounds could causes for varying results as each person could show different reactions to Inflammatin based on their race and genetics. We can control this by furthering narrowing down the type of subjects we are looking for to do this experiment, i.e all caucasian subjects. Having currently ill or at high risk subjects could also possibly show more of a reaction to Inflammatin than those are not at risk. Along with specifically experimenting on a specific race, we could also chose people who are all not at risk or at a high risk.
