According to the Central Limit Theorem, the frequency curve made from means from numerous large random samples or repetitions of the same size taken from a population will have a bell-shaped curve, also known as a normal distribution. This is because the means will tend to cluster around the population mean, resulting in a symmetrical distribution with most of the data falling close to the mean.
