The whole point of a nominal variable is that is has no numerical value associated with it. With a binary measure you can allocated the values 1 and 0 or +1 and -1 for observations where the attribute is present or absent. If there are more than 2 values that the nominal variable can take then you can allocate any numbers that you want but in all cases the numbers do not have a value: they are simply symbols which can help for sorting and for binary comparisons.

What are nominal values?
Nominal values are the values that a component is specified to be. For example, the nominal value of a 10K resistor is 10K. Its actual value may vary, though, based on its tolerance.
What is 2 to the 27th power?
It is two multiplied by itself 27 times. I leave the actual numerical amount as an exercise for the student.
What is the numerical value of the number FIVE?
Oh honey, FIVE is a word, not a number. The numerical value of the word "FIVE" is 42 if you're talking about its ASCII value. But if you're looking for the numerical value of the actual number 5, well, that's just 5. Math can be a real hoot, can't it?
What is x2 81y2 equal to?
x2 - 81y2 = (x + 9y) (x - 9y)The actual numerical value depends on the values of 'x' and 'y'.
How wide is a 2 X 8?
Let's define a few things, nominal refers to the name of the product and actual refers to literal or real dimensions of the product.Products are either finished or unfinished (a.k.a. full cut).Both of these products use the same label (2x8)" example, but the actual size of the finished product in the above would be ~(1.5x7.5)" The unfinished product measures the size stated in the name ~(2.0x8.0)"; hence described as full cut.
