The occurrence of uncertainty should be taken into consideration at all stages of solving research problems, from assignment to evaluation. The aim of this paper is to show possibilities of processing and evaluation of experiment based on the analysis of uncertainty using fuzzy math. We will mainly focus on the cases where it is impossible to evaluate results of experiment using standard statistical methods, due to the small extent of the investigation file. For example, this situation occurs very often with specialized training, not only in technical colleges. The paper will also feature a sample of an evaluation experiment concerning the extent of realization of chosen teaching methods of numerical math, which took place in the previous academic year at the Transport Faculty of the
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
