The Central Limit Theorem is a powerful theorem in statistics that allows us to make assumptions about a population and states that a normal distribution will occur regardless of what the initial distribution looks like for a su ciently large sample size n. The Central Limit Theorem. Very few of the data histograms that we have seen in this course have been bell shaped. When we have come across a bell shaped distribution, it has almost invariably been an empirical histogram of a statistic based on a random sample.
