Explanation / Answer
Payor is categorical
As the name suggests, categorical variables are those variables that fall into a particular category.
we can count categorical data.
Ex:How many brides parents
categorical variable, also called a nominal variable, is for mutual exclusive, but not ordered, categories. For example, your study compare four different payor types. You can code the four payortypes with numbers if you want, but the order is arbitrary and any calculations (for example, computing an average) would be meaningless.
value rating is ordinal variable
A ordinal variable, is one where the order matters but not the difference between values. For example, you might ask patients to express the amount of pain they are feeling on a scale of 1 to 10. A score of 7 means more pain that a score of 5, and that is more than a score of 3. But the difference between the 7 and the 5 may not be the same as that between 5 and 3. The values simply express an order..
couples income, brides age ,wedding cost attendance are measured and doesnt include 0 so interval variables.
