Assessing the impact of international intervention on justice indicators: a statistical evaluation of legal compliance, judicial independence, and crime reduction

Abstract

The research presented here examines the impact of international intervention in justice-related indices over a wide range of countries. We utilized a dataset that consisted of 200 observations to measure the groups with and without intervention against four important variables: Human Rights Score, Judicial Independence Score, International Legal Compliance, and Crime Rate Index. Through descriptive statistics, the intervention countries were significantly consistently seen with better governance and lower crime metrics. The use of Welch’s ANOVA and assumption checks via Levene’s test and Shapiro–Wilk normality testing were among the statistical analyses that validated these differences as being statistically significant. The use of Q-Q plots and mean plots with confidence intervals further corroborated these findings. The conclusion drawn from the results is that international interventions are positively related to the integrity of the judiciary, the enforcement of the law, and the reduction of crime rates. These outcomes are of great importance because they not only provide empirical support for the global legal collaboration and intervention strategies that aim to further strengthen the justice systems but also for the policies favoring such scenarios.
