Systematic/Statistical errors [distinguish]

[ChrisVer]

I have one fast question. How can people in some results, distinguish between systematic and statistical errors? So that they can write: $x= A^{\pm \delta B (stat)}_{\pm \delta C (syst)}$?

I am trying to do the same with a report of mine, but I am not quite sure about whether that's possible or not.

It is possible, but you need to analyse the design of the experiment in detail.
