Abstract

The central limit theorem is the most fundamental theory in modern statistics and quite an important concept in biostatistics, and data science. The central limit theorem states that the sampling distribution of the mean for a variable will approximate a normal distribution regardless of that variable’s distribution in the population, when the sample size is large. In real life we cannot repeat studies (resampling) many times to estimate the sampling distribution of the mean. Hence only a simulation-based illustration is possible to understand the concept of central limit theorem. Present study aims to provide a clear understanding of the concept of central limit theorem with the help of simulated data using R codes.
