1. Break Down the Problem

We need to identify which option cannot be classified as a nominal scale among the given options: marital status, blood group, ranking, and gender.

2. Relevant Concepts

• Nominal Scale: This is a categorical scale where the order does not matter. It is used for labeling variables without any quantitative value.
• Examples of Nominal Scale: Marital status, blood group, and gender are all variables that represent categories without any inherent order.

3. Analysis and Detail

1. Marital Status: Categories include single, married, divorced, etc. This is nominal since it labels different categories.
2. Blood Group: Categories include A, B, AB, O. This is also nominal.
3. Ranking: This involves an order or hierarchy (like 1st, 2nd, 3rd), meaning it is ordinal, not nominal.
4. Gender: Categories such as male, female, and other, which is nominal.

4. Verify and Summarize

From the analysis, marital status, blood group, and gender can all be classified as nominal scales, while ranking cannot because it implies a specific order.

Final Answer

Ranking cannot be called an example of a nominal scale.
