Final answer:
Assigned numbers do not alter the nature of a nominal variable. They are used as labels to distinguish between different categories.
Step-by-step explanation:
A nominal variable is a categorical variable that represents different categories or groups. Assigned numbers can be used to represent the different categories or groups in a nominal variable, but they do not alter the nature of the variable. The assigned numbers are simply labels or codes used to distinguish between the different categories.
For example, if we have a nominal variable representing different colors, we can assign the numbers 1, 2, 3, etc. to represent each color. However, the assigned numbers do not have any inherent mathematical meaning or relationships. They are just convenient labels to identify the different categories.
