The mystery of the CHI SQUARE. Is it CHEE square Or CHAI Square?!. Chi Square X 2 goodness of fit. There is a single test that can be applied to see if the observed sample distribution is significantly different in some way from the hypothesized population distribution.By cachez

Chi-Square Test. A fundamental problem is genetics is determining whether the experimentally determined data fits the results expected from theory (i.e. Mendel’s laws as expressed in the Punnett square).
