Accepted Answer

### Problem 19: Football
# Brief Explanations:
- **Qualitative/Quantitative**: The data (team names) are non - numerical labels, so they are qualitative.
- **Level of Measurement**: The ranks (1st, 2nd, etc.) have an order, but the differences between ranks (e.g., between 1st and 2nd) don't have a meaningful numerical interpretation. So it is ordinal level.

# Answer:
Qualitative, Ordinal level (because the teams are ranked, so there is an order, but the "distance" between ranks isn't meaningful; the data are labels for teams with a ranking order).

### Problem 20: Politics
# Brief Explanations:
- **Qualitative/Quantitative**: The data (political party names) are non - numerical categories, so they are qualitative.
- **Level of Measurement**: The parties are just different categories with no inherent order (e.g., Republican isn't "more" or "less" than Democrat in a non - arbitrary way), so it is nominal level.

# Answer:
Qualitative, Nominal level (the political parties are distinct categories with no natural order).

### Problem 21: Top Salespeople
# Brief Explanations:
- **Qualitative/Quantitative**: The data (region names) are non - numerical categories, so they are qualitative.
- **Level of Measurement**: The regions are just different categories with no inherent order (e.g., Southeast isn't "more" or "less" than Northwest in a non - arbitrary way), so it is nominal level.

# Answer:
Qualitative, Nominal level (the regions are distinct categories with no natural order).

### Problem 22: Fish Lengths
# Brief Explanations:
- **Qualitative/Quantitative**: The data (lengths in inches) are numerical values representing quantities, so they are quantitative.
- **Level of Measurement**: The lengths have a true zero (a length of 0 inches means no length), and differences and ratios are meaningful (e.g., a 24 - inch fish is twice as long as a 12 - inch fish). So it is ratio level.

# Answer:
Quantitative, Ratio level (the lengths are numerical values with a true zero, and ratios/differences are meaningful).
