Thus, the central limit theorem is the foundation for many statistical procedures, including quality control charts, because the distribution of the phenomenon under study does not have to be normal because. Because the square of a standard normal distribution is the chisquare distribution with one degree of freedom, the probability of a result such as 1 heads in 10 trials can be approximated either by using the normal distribution directly, or the chisquare distribution for the normalised, squared difference between observed and expected value.
