Glossary Quality Control / Term
A statistic that lets you compare observed to expected frequencies. If none of the expected frequencies is too small, the statistic follows a chi-square distribution. A large chi-square statistic leads to a conclusion that two distributions are different. A small chi-square statistic leads to a conclusion that two distributions are similar. Also known as a Portmanteau statistic.
