網頁Pearson's chi-square distribution formula (a.k.a. statistic, or test statistic) is: χ 2 = ∑ ( O − E) 2 E. A common use of a chi-square distribution is to find the sum of squared, normally distributed, random variables. So, if Z i represents a normally distributed random variable, then: ∑ i = 1 k z i 2 ∼ χ k 2.
