The Problem of Statistical Estimation,Observations constitute the basis of a statistical experiment: these may be numerical data or data of some other nature obtained as a result of a statistical experiment. The problem is to make, based on these data, some definite and sufficiently reliable conclusions concerning the object under investigation.
