Are the numbers on a baseball uniform an example of nominal

Solution

Uniform numbers are worn on the uniform of each baseball player and baseball coach. The uniform numbers are used for the purpose of easily identifying each person on the field as no two people from the same team can wear the same number.

As this is only for identification, it is an example of nominal data.

Only if the number has more significance in order or code, then it can be ordinal data.

But here this is only nominal data.
