Qualitative variables, also known as categorical variables, can be divided into two main types:
1. **Nominal Variables**: These are categories that do not have a specific order or rank. Examples include gender, color, or types of cuisine. In nominal data, each category is distinct, and one category cannot be considered higher or lower than another.
2. **Ordinal Variables**: These are categories that have a specific order or ranking among them. Examples include education level (e.g., high school, bachelor's, master's, doctorate) or customer satisfaction ratings (e.g., very dissatisfied, dissatisfied, neutral, satisfied, very satisfied). Even though ordinal variables have an inherent order, the intervals between the categories are not necessarily consistent or meaningful.
Understanding the distinction between these two types of qualitative variables is important for selecting the appropriate statistical methods for analysis.
