Attribute Data - Lean Six Sigma Glossary

Attribute data, also known as categorical data, is a type of data that is used to describe qualities or characteristics of an entity. Unlike numerical data, which can be quantified and measured, attribute data can only be described in terms of its properties or attributes.

Types of Attribute Data

There are two types of attribute data: nominal and ordinal.

Nominal Data

Nominal data refers to categories or names that have no inherent order or structure. Examples of nominal data include gender, hair color, and eye colour. Nominal data is further divided into binary and non-binary data. Binary data has only two categories (e.g., male or female), while non-binary data has more than two categories (e.g., red, green, blue).

Ordinal Data

Ordinal data, on the other hand, refers to categories that have an inherent order or structure. Examples of ordinal data include education level (e.g., high school, bachelor’s degree, master’s degree), income level (e.g., low, medium, high), and satisfaction level (e.g., very dissatisfied, dissatisfied, neutral, satisfied, very satisfied).

Uses of Attribute Data

Attribute data is used in a variety of fields, including business, psychology, and health sciences. In business, analysts often use attribute data to segment customers based on their characteristics, such as age, gender, income, and education level. Organizations use this information to develop targeted marketing campaigns. And to better understand the needs and preferences of different customer groups.

In psychology, researchers use it to study and describe human behavior and attitudes. For example, researchers may use attribute data to classify individuals based on their personality traits, such as extroversion and neuroticism.

In the health sciences, researchers use it to describe and classify diseases, conditions, and symptoms. For example, researchers can use it to classify a disease as acute or chronic. They can also use it to describe the severity of a condition (e.g., mild, moderate, severe).

Collection of Attribute Data

You can collect Attribute data through a variety of methods, including surveys, interviews, and observational studies. When collecting such data, it is important to choose the appropriate data collection method and to design the survey or interview questions carefully to ensure that the data collected is accurate and relevant.

Data Analysis

You can analyze Attribute data using a variety of statistical techniques, including frequency distributions, cross-tabulations, and chi-square tests. You can use Frequency distributions to describe the distribution of categories in a data set. Or use cross-tabulations to examine the relationship between two or more categorical variables. You can also use Chi-square tests to test the hypothesis that there is a relationship between two categorical variables.
