Central Limit Theorem under Different Continuous Distributions: A Simulation-Based Investigation of Factors Affecting Convergence

Öz

The Central Limit Theorem (CLT) is one of the cornerstones of statistics and probability theory. In this study, the practical validity of the CLT was examined through simulations conducted on different continuous distributions such as Beta, Exponential, Gamma, Log-Normal, and Weibull. While the literature generally addresses the convergence of the sample mean to normality in broad terms, in this study, the rate of convergence and the effect of sample size were analyzed using different metrics, including variance, skewness coefficient, maximum approximate error (MaxError), and the Berry bound based on the Berry-Esseen theorem. The simulation results provide a detailed perspective on the reliability and limitations of the CLT. The history of the CLT dates back to early theoretical studies and, over time, it has been recognized as a tool that allows the distribution of sample means to approach the normal curve even when the underlying population is not normal. This property has made the CLT a fundamental concept in various fields, including political science, computer science, psychology, medical research, and engineering. Despite its widespread use, the practical outcomes of the CLT are often not sufficiently understood in terms of the effects of factors such as sample size and skewness on convergence. In this study, simulation methods were applied to different continuous distributions. Consequently, in addition to classical measures of mean and variance, additional criteria were considered. Thus, the rate at which distributions approach normality and the conditions under which the CLT can be reliably applied were evaluated more comprehensively.
