Example 1a: SCORING

There is evidence of an internal cross-classification based on the animals in the boxes. Elephant, tiger, and dog fit the wild-land box (if we consider that a dog may be wild), shark and whale fit the wild-sea box, chicken fits the dark-land box, and seal fits the dark-sea box. Therefore this represents one of our special cases.

1. Column groups
   • FIRST, are both groups levels of the same variable?
     • land and sea are levels of a variable.
   • SECOND, is there corroborating evidence?
     • Step 1: check property label.
     • land and sea are levels of where. 2 points
2. Column property
   • Do both column groups fit the property?
     • land and sea are levels of where. 1 point
3. Row groups
   • FIRST, are both group levels of the same variable?
     • wild and dark are levels of a variable. 0 points
4. Row property
   • No points for property because row groups are not levels of a variable. 0 points
5. Box Labels
   • Missing, so no points. 0 points
6. Animals
   • Does the animal fit the box?
   • We may award points for 7 of the 8 animals, as discussed above. 7 points
