WebMay 3, 2024 · Central Limit Theorem Explained. The central limit theorem in statistics states that, given a sufficiently large sample size, the distribution of the sample mean for a variable will approximate a normal distribution regardless of that variable’s in the population distribution. Unpacking the meaning of that complex definition can be difficult. WebThe Empirical Rule is an approximation that applies only to data sets with a bell-shaped relative frequency histogram. It estimates the proportion of the measurements that lie within one, two, and three standard deviations of …
