Independent and Dependent Variables
The dependent variable in the experiment is the amount of Inflammotin in the blood of the subject. The amount of Imflammotin would be the dependent variable because it is the variable that is being measured.
The independent variable in the experiment is the dose of Lipopolysaccharide. The dosage of Lipopolysaccharide is the independent variable because it is the variable being changed.
Number of subjects per group
Experimental subjects are to be selected in order to reflect a wide variety of demographics within the target age group of 55 to 85 years. Within the 20 person groups, we will have an equal amount of males and females (10 of each). We are also incorporating racial demographics in our subject selection. Our goal is to gather a sample size with healthy ethnic diversity, with specific attention being given to participants of Caucasian, Hispanic, African-American and Asian descent.
