Hate asking such a general question, but I'm so unfamiliar with statistics in general that I don't know what to search or where to find the answer.
I'd like to learn how to manipulate errors. Like, if I had a function $f\left(x,y,z\right)$, and I knew $\sigma_x,\sigma_y,\sigma_z$, what the error of $\sigma_{f}$ is.
