Hello, I'm working on an assignment in molecular biology, measuting activity of an enzyme. Our results are pretty bad, and we wonder if we can say anything based on our data. To remedy this, we want to do some statistics, but don't know how to... this is what we do:
a=slope from linear regression/constant b=a/mean of standard samples c=b*concentration >From the linear regression we can find the standard error and thus standard diviation. The 'mean of standard samples' also carries a standard diviation. The concentration is calculated from a measurement where we also can find the standard diviation. How do I combine all theese standard diviations and other errors that we can quantify? Or rather: where can I find good information on combining SD's? Thanks a lot!
