EX POST FACTO експеримент

During the past century the ex post facto experiment was developed as a kind of experiment suitable for social sciences and its experimental character was (and still is) often contested. However, since the ex post facto experiment has been accepted by many authors as an appropriate kind of experiment in the social sciences, this paper presents the ways in which the ex post facto experiment is defined. It also deals with its types, different opinions on whether this form of research is experimental or not, as well as the advantages and difficulties in comparison to other types of experiments.
