Sample Size Web3.2 Chi-Square Distribution The chi-square distribution is related to the normal distribution. If X = P k i=1 Z 2 where the Z iare independent standard normal distributions, then the random variable Xfollows a chi-square distribution with degrees of freedom k. The chi-square distribution is de ned by a single parameter: the degrees of freedom k.
In probability theory and statistics, the chi-squared distribution (also chi-square or -distribution) with degrees of freedom is the distribution of a sum of the squares of independent standard normal random variables. The chi-squared distribution is a special case of the gamma distribution and is one of the most widely used probability distributions in inferential statistics, notably in hypothesis testing and …
