Final answer:
The variable that is categorical but not ordinal among the provided options is B) Zip code, which categorizes regions without implying any hierarchical order.
Step-by-step explanation:
The student asks which of the given variables is categorical but not ordinal. In order to determine this, we need to understand the difference between categorical and ordinal variables. A categorical variable places individuals or items into different groups or categories where the order does not matter. Ordinal variables are also categorical but with a meaningful order. Considering the options provided:
- Income (quantitative continuous)
- Zip code (categorical)
- Size of clothing items (ordinal categorical)
- A ten-point scale customer satisfaction rating (ordinal categorical)
- Education level (ordinal categorical)
The variable that is categorical but not ordinal is B) Zip code since it categorizes regions but does not imply any order of hierarchy or importance.
