Abstract. Economic freedom in the sphere of methodological provision of economic researches and a number of related concepts are still causing problematic situations.
Difficulty of both unanimous and conceptual evaluation of appearances of economic freedom in the research process exists. The key moment complicating the problem is to carry out the process in two various planes. On one hand the appearances of economic freedom in reality and unanimous interpretation of essence disclosure of its caused occurrences, on the other hand the problems of existence of “freedom” of the researcher make the status of reality of the obtained conclusions doubtful.
Our aim in this Article is to provide interpretation of appearance of the economic freedom problem not wholly, but only in our mentioned context and its less or more related concepts from methodological point.

Key words: freedom, choice, coincidence, possibility, probability.
