Application of Statistics for Evaluating the Efficiency of Banking Services

Abstract

The relevance of this study is determined by the growing need to improve the efficiency of banking services and the necessity of applying objective methods to assess their performance. The aim of the article is to examine methodological approaches to using statistical tools for evaluating the effectiveness of banking institutions and to justify practical recommendations for analyzing banking services based on statistical data.

The methodological basis of the study consists of statistical and comparative analysis methods, as well as a systematic approach, the application of which made it possible to comprehensively assess the effectiveness of banking institutions. The work uses descriptive statistics tools, in particular the calculation of mean values, medians, coefficients of variation, and integral efficiency indices, which facilitates an objective comparison of the financial condition of banks. The use of these tools ensures the representativeness of the analysis of the level of efficiency of institutions within the sample under study.

The study found that statistical methods are an effective tool for objectively assessing the quality of banking services, ensuring an adequate level of transparency in the activities of financial institutions, and optimizing management processes. The use of return on assets (ROA), return on equity (ROE), the integrated index of banking services efficiency (hereinafter referred to as I_EBP), as well as summary statistical characteristics (mean, median, and coefficient of variation) contributes not only to the quantitative measurement of the level of efficiency, but also to the objective assessment of the degree of its stability and the nature of differentiation between institutions.

The conclusions indicate that the use of statistics makes it possible to objectively identify the strengths and weaknesses of banking services, increase customer confidence, and contribute to the optimization of internal processes of financial institutions. The practical significance of the results obtained lies in the possibility of using them to form bank development strategies, improve service quality control systems, and increase the competitiveness of banking products in modern conditions.
