THE USE OF F-TEST ON CPI DATA

Abstract

This study examines whether there is a statistically significant difference in the variability of corruption levels between European and Asian countries using the Corruption Perception Index (CPI). The CPI scores, published by Transparency International, are used as a proxy for perceived public-sector corruption. An F-test is employed to compare the variances of CPI scores for selected countries from Europe and Asia. Prior to analysis, the data are tested for normality to satisfy the assumptions of the F-test. The results indicate whether the dispersion of corruption perception differs significantly between the two regions, providing insights into regional heterogeneity in governance quality. The findings contribute to comparative institutional analysis and offer empirical evidence on regional differences in corruption perception, which may be useful for policymakers, researchers, and international organizations concerned with governance reforms and anti-corruption strategies.
