This Paper is continuation of the authors’ previous researches. Using the correlation analysis authors proved the hypothesis of the presence of the connection between the index of economic freedom and national cultural dimensions (after Hofstede). They also proved it between some indicators of the economic freedom and national cultural dimensions (after Hofstede) using the program Curve Fitting Toolbox (Mathlab). The analysis was done using 19 indicators from 35 European countries: 6 indicators of the national cultural dimension and 13 indicators of economic freedom. This research helped to find out, which indicators of the national cultural dimensions can influence the development of economic freedom in the country. For the answer to the question "How can the nation's mentality affect the level of economic freedom in the country?" authors plan to study deeper the mental dimensions, in particular to test the mental performance of S. Schwartz, C. Hampden-Turner, F. Trompenaars.
