Features of Categorical Data
Understanding the features of categorial data can help to choose appropriate statistical methods and make meaningful interpretations.
Here are some key features of Categorial Data:
Categorial Data
Categorial data is further sub-classified into nominal and ordinal Data.
Nominal Data: Nominal data represents unordered categories or categories without any inherent order.
- Example: Colors, gender, and types of animals.
Ordinal Data: Ordinal Data represents ordered categories or categories having systematic order or ranking.
- Example: Education level (high school, college, graduate).
Mutually Exclusive
The categorial data are mutually exclusive as each observation falls into exactly one category, and no overlapping happens between categories.
Countable Categories
The categories in the categorial data are countable and distinct. They are used in frequency distribution and bar charts.
No Arithmetic Operations
The arithmetic operations are not meaningful in categorial data as you cannot perform operations like the average of categories.
Mode as Measure of Central Tendency
In categorial data, the mode is often used to describe the central tendency. It represents the most number of times a category has occurred.
Chi-Square Test
One famous statistical test for categorical data analysis is the chi-square test. It helps to determine the significant associations between two categorical variables.
Categorical Data
Categorical data classifies information into distinct groups or categories, lacking a specific numerical value. It refers to a form of information that can be stored and identified based on their names or labels. Categorical Data is a type of qualitative data that is easily measured numerically.
In this article, we will learn about, what is categorial data, types of categorical data, and some real-life examples.
