LAB 1 WRITE-UP
Independent and Dependent Variables
(Identify the independent and dependent variable in the mini-problem.)
The Independent variable is the dose amount of lipopolysaccharide that is given to each subject. The dependent variable is the amount of the inflammotin that is present in the subject after the dose has been given.
Number of subjects per group
(Discuss considerations of how subjects are to be selected.)
Sources of Error and Bias
(What are some of the potential sources of error or biases that could affect your results and how would you control for them?)
Physical Activity - Active participants could have different occurrences of inflammation so participants will not be able to exercise during the experiment. However it would be important to check inflammation levels before running the trial to know the base levels of inflammation for each individual subjects.
Current Medication/ Pre-existing medical conditions - Participants will be screened for medications that can interact with lipopolysaccharide and will not be allowed to take any other anti-inflammatory medication.
Diet - We are attempting to control for the possible interactions of individual diets with fasting however there may still be an overall effect of diet.
Geographic Area - Our participants are being selected from a specific area (Sun City, AZ) so the results may not be applicable to other parts of country.
