To determine whether each column represents a nominal or ordinal variable, we need to understand the definitions:
- **Nominal variables** are categories without a specific order (e.g., Gender, Hair Color).
- **Ordinal variables** have a meaningful order but no consistent difference between the categories (e.g., Rank, Satisfaction Ratings).
Here’s an analysis of each variable:
1. **Rank**: Ordinal - This variable represents the position in a sequence or order (e.g., 1st, 2nd, 3rd), which indicates a hierarchy.
2. **Book**: Nominal - This variable represents different book titles, which are categories without any inherent order.
3. **Author(s)**: Nominal - This variable consists of names of authors, which are categories without any specific order.
4. **Language**: Nominal - This variable represents different languages, which are categories with no inherent order.
5. **Year Published**: Ordinal - While years are numerical values, they can be treated as categories with an order (before and after), indicating a sequential timeframe.
6. **Sales**: Neither nominal nor ordinal – This variable is quantitative and represents numerical values (e.g., number of copies sold), which do not fit within these categories.
7. **Genre**: Nominal - This variable represents different categories of books (e.g., Fiction, Non-Fiction) without any order.
In summary:
- **Rank**: Ordinal
- **Book**: Nominal
- **Author(s)**: Nominal
- **Language**: Nominal
- **Year Published**: Ordinal
- **Sales**: (Quantitative, not nominal or ordinal)
- **Genre**: Nominal
- **Nominal variables** are categories without a specific order (e.g., Gender, Hair Color).
- **Ordinal variables** have a meaningful order but no consistent difference between the categories (e.g., Rank, Satisfaction Ratings).

7. **Genre**: Nominal - This variable represents different categories of books (e.g., Fiction, Non-Fiction) without any order.
In summary:
- **Rank**: Ordinal
- **Book**: Nominal
- **Author(s)**: Nominal
- **Language**: Nominal
- **Year Published**: Ordinal
- **Sales**: (Quantitative, not nominal or ordinal)
- **Genre**: Nominal
