Hi all,
I'm currently doing my masters thesis about blood pressure monitors.
I'm compairing them on repeatability using a simulator.
Now i have 5 different devices with each 3 simulations x 85 measurements. (Simulations are High blood pressure, low and normal)
I did the basic thing like look at the mean values and standard deviations but want to go further.
What I already tried to do:
T-test;
I used excel to calculate this but the really really small;
Seems like I'm doing something wrong here.
Used my 2 columns in excel, two sided and coupled.. should be correct.
Bland Altman analysis;
Seems like my measurements are not different enough from one another to have a good analysis since i'm only getting 3 different points;
So my question to you guys is if somebody point me in the right direction on which analysis should be good for this research.
I've posted an example of my measurement of 1 device in attachement. (with no calculations on this one)
Thank you in advance!
