Is binominal the same as boolean?

Question

In the case of describing an attribute type which has two values (yes or no) is binominal the same as boolean? A source would be great.

Answer 1

I wouldn't say that. Binominal stresses that the item on hand has two names, rather than two values. It is not so appropriate. I'd rather use bivalued for a discrete attribute having two cases, such as black/white.

Boolean specifically applies to variables taking values in $\{0,1\}$, which can be mapped to logical values false and true. Boolean algebra (computation with these numbers) parallels the rules of propositional calculus.
