1. ### Break Down the Problem

To identify a categorical variable, we need to understand what a categorical variable is. A categorical variable represents types or categories of data, which can be divided into groups or classifications.

2. ### Relevant Concepts

• Categorical Variable: A variable that can take on one of a limited, and usually fixed, number of possible values, assigning each individual or other unit of observation to a particular group or nominal category.
• Examples of categorical variables include gender (male, female), color (red, blue, green), etc.

3. ### Analysis and Detail

We will evaluate each option to determine if it fits the definition of a categorical variable:

1. Gender: Represents categories (male, female) - This is a categorical variable.
2. Object: This term is vague but typically refers to things rather than categories - This might not be categorical.
3. Number: Represents numerical values which are typically quantitative - This is not a categorical variable.
4. Alphabet: This refers to letters which can be considered categories but is more ambiguous than gender.

4. ### Verify and Summarize

From the analysis above:

• Gender is clearly a categorical variable.
• Object is unclear but likely not categorical.
• Number is not categorical.
• Alphabet is ambiguous and may not be strictly categorical depending on context.

Final Answer

The categorical variable among the options is Gender.
