Gender and psychology concentration are cross-classified for N = 100 graduate students, resulting in a 2 x 5 contingency table. Estimating the nature and magnitude of the association between these variables by legacy statistical methods is inappropriate owing to computational and interpretative difficulties. However, obtaining and interpreting the maximum-accuracy model for these data is straightforward.

To assess if going first is an advantage in the card-game cribbage, an experienced human cribbage player competed against a computer for 100 games. When findings were analyzed using non-directional chi-square analysis there was no statistically significant effect.
