Statistics is about trying to learn dependable things about the real world based on measurements of it. Statustics involves probability with dealing with fundamentsl unknowns. Usually the observations we have are related to some underlying value or state of the world, but also have some level of randomness. If we knew the underlying value/state, we may know the statistical proeprties of the observations, the 'job of statsitcis' is to invert theis process, to find out about the unknown state of the world, from these probabalistic observations.
