The word, variable, has several synonyms, such as changeable or unsteady. Our set of rules tells us that a variable is a noun, not an adjective, and represents a class of outcomes that can take on more than one value. For example, hair color is a variable that can take on the values of red, brown, black, blonde, and these days green, orange, and (I swear) puce. (I saw it outside my office this morning!) Other variables would be height (tall or short), weight (128 pound or 150 pounds), age at immunization (6 weeks or 18 months), number of words remembered, time off work, party affiliation, and so on. The one thing these traits have in common is that the variable (such as party affiliation) can take on any one of several values (such as Republican, Democrat or Independent)."
