CHIDIST compares the Chi square value to be given for a random sample that is calculated from the sum of (observed value-expected value)^2/ expected value for all values with the theoretical Chi square distribution and determines from this the probability of error for the hypothesis to be tested.
CHIDIST fergeliket de Chi- kwadraat- wearde foar in willekeurige stekproef dy' t berekkene wurdt út de som fan (waarnommen wearde - ferwachte wearde) ^2/ ferwachte wearde, foar alle wearden, mei de teoretyske Chi- kwadraat- ferdieling en berekkent hjirmei de kâns dat de teste hypoteze fout is.
