The results of the basic course Mathematics for Economist at the University of Economics in Prague in winter semester of the academic year 2017/2018 are statistical analysed in present paper. We shall study dependence of the results of examinations of 879 students in this course on the examiners (ten examiners took part in the examinations at this course). We shall use different statistical methods for the analysis (chi square test of independence in contingency table, analysis of variance, Scheffé's method etc.). The obtained results can be used for improving bachelor exams in mathematics at the department of mathematics in coming years.
