I've an ongoing experiment. We're trying to determine if it's possible to detect if a bunny is infected with a disease through an electronic device over a period of time of 1 month. Since we couldn't get a higher volume of the virus we have to work with 3 control subjects and 3 infected subjects.
The problem is that we didn't realize that the subjects involved had two different blood types( A & B). So now we have Group A (2 control & 1 infected) and Group B (1 control & 2 infected).
The difference between blood types changes the magnitude obtained from the instrument.
My questions are, what type of analysis should I use (Specially for small samples/Data-sets)? Am I still able to divide them into control and infected groups? Is this problem reliable (in terms of statistics)? Is a test of standard deviations the best way to approach this?
Thanks in advance
