i apologize for the simple question, but i have no experience with stats. i have a data set that i am trying to analyze. i have calculated the mean and SEM. at this point i want to normalize all my means to a control. my question is do i have to re-calculate my SEM.

for instance

if i have

data set 1: 4, 4.2, 3.9, 4.7 -- mean of 4.2 and SEM of 0.177

data set 2: 0.5, 0.6, 0.7, 0.4 -- mean of 0.55 and SEM 0.0646

now i want to normalize my first set of data to the second. meaning i want to set my second set of data to a mean of 1....giving me the mean for my first set of 7.636. my question is what do i need to do to my SEM now?

thanks!!
