Independent and Dependent Variables
Independent variable: dosage. The dosage would be considered to be independent since it is not affected by other factors in the experiment Dependent variable: protein that causes inflammation in blood. The inflammation is dependent on the dosage, therefore, it is the dependent variable.
5 groups—10 mg group, 8 mg group, 6 mg group, 4 mg group, 2 mg group. We chose to use intervals of two milligrams because it is a small enough interval between each group to see if it will still be effective while using the least amount of medicine, therefore it will reduce cost.
20 total subjects per group, each group consisting of 10 males and 10 females.
The age of the subjects is 65 and up, struggle with inflammation issues, Out of those who sign up, use a random number generator to randomly choose 10 males and 10 females per group. This will allow the groups to be as random as possible. When selecting people of different age groups, we will avoid bias of getting an unbalanced group as compared to the others. An example of this would be a group that has lots of 65 year old's and another group of 90 year old's.
Sources of Error and Bias
Age range in each group—if the group isn’t balanced (has too many 65 year olds compared to a group that has too many 90 year olds) this could cause issues. We can fix the problem by balancing the ages in each group.
Subjects could have a protein deficiency which could throw off the data. We will avoid this by having subjects take a physical and rule out all protein related illnesses
If the elderly are already taking medicines that affect inflammation this could throw off the data. We will avoid this by excluding people who are taking similar medications
