Abstract :
The purpose of this paper is to analyze statistically vague data obtained from the observation of human feelings. Considering that the data mentioned above are the realizations of the fuzzy random variables (FRV), the method for estimating their statistical properties is proposed. First, using the set representation approach, the reasonable definition of FRV is proposed, which may be a mathematical model for the data being intrinsically and simultaneously vague and random. Secondly, the statistical moments for the proposed FRV and their estimates are investigated. Finally, the proposed FRV are tried to apply the analysis of the statistical properties of the data obtained from the questionnaire on taste of (mainly middle aged and old) persons for the bicycle designs
