In today’s world, it’s crucial to understand and use data effectively to make informed decisions. This blog discusses categorical data, its types, features, examples, and issues, and how Voxco, a leading insights platform, can help businesses leverage this data for growth and improved customer experiences in today’s data-driven world.

What is categorical data?

Categorical data is qualitative data that can be categorized into distinct groups or categories. Such categories usually come in the form of labels or names representing different attributes or characteristics of a data set. Categorical data has no inherent order or ranking, which is contrary to numerical data, so it is important for grouping and analysis purposes.

An example is customer satisfaction, where the survey responses could be “very satisfied,” “satisfied,”, “neutral,”  “dissatisfied,” or “very dissatisfied.” Such data is of good importance to market researchers because it helps them split and understand different groups of customers.

What is the difference between pricing analysis and competitive pricing analysis?

The two terms are distinct and differ in their core focus. 

Pricing analysis is a broader term with focus beyond competitive pricing. This includes understanding and factoring incustomer behavior, their willingness to pay, and competeritor’s strategy to design a pricing strategy that aligns with company’s goal. 

The focus of competitive pricing analysis is to determine how to craft a pricing strategy for your offerings to maintain competitiveness. It enables you to achieve three insights: 

  • Strengths and weaknesses of your strategy and your competitors. 
  • Potential opportunities to refine the pricing strategy. 
  • The value proposition to set your brand apart from the competition. 

Examples Of Categorical Data

To better understand categorical data, let’s delve into some examples. These examples span various domains, such as demographics, survey responses, and product categories, highlighting how this is used to classify and analyze information effectively.

Demographic Information: Age groups (child, teenager, adult, senior), marital status (single, married, divorced, widowed), and education levels (high school, undergraduate, postgraduate).

Survey Responses: Categories of customer feedback, either positive, neutral, or negative; brand preferences, as Brand A, Brand B, or Brand C; and product satisfaction level, either satisfied or unsatisfied.

Product Categories: Type of products (electronics, clothing, groceries), type of services (premium, standard, basic), and subscription levels (free, basic, premium).

What Are The Types Of Categorical Data ?

The most common divisions of categorical data are nominal  and ordinal data. Each of these has its own characteristics and use, and therefore, understanding the two becomes very important for the effective analysis and application of data.

1.Nominal Data

Nominal data is made up of two or more categories that are not arranged in any particular order. They are incapable of being measured or ranked in a clear hierarchy. Using nominal data, variables lacking a quantitative value or order are labeled.

The most basic measure level, nominal data, is regarded as the cornerstone of statistical analysis. Nominal data includes Hair, color, gender, race, location of residence, and college major are a few examples of nominal data.

2. Ordinal Data

Data with categories or groups that have a natural rank order is known as ordinal categorical data. The disparity in the ranks, though, might not be equal. This kind of quantitative data is statistical in nature and has variables that are in natural order categories.

Because ordinal data allows respondents to make relatively easy choices even in cases where the underlying attribute is challenging to quantify, it is frequently employed in social science and survey research. Histograms, visual aids, bar charts and pie charts are readily used to illustrate this kind of data.

  • Customer Satisfaction: Very Dissatisfied, Dissatisfied, Neutral, Satisfied, Very Satisfied

  • Socioeconomic Status: Low income, Middle income, High income

  • Severity Levels: Minor, Moderate, Severe, Critical


  • Gender: Male, Female, Non-binary

  • Ethnicity: Asian, Hispanic, Black, White

  • Type of Car Owned: Sedan, SUV, Truck, Coupe

  • Brand Preference: Nike, Adidas, Puma


Features Of Categorical Data

The unique features by which categorical data are distinguished from other types of data make it particularly useful for doing specific types of analysis and decision making. Understanding such characteristics helps one to choose the right methods for data collection, analysis as well as interpretation. Categorical data is distinguished from other types of data by several unique features: 

  • Distinct Categories: Every value belongs with its own category which makes it easy to break down so as to aid in analysis. It is key to pull together those points that can be seen as similar and find common characteristics at category level so as to see any desired behaviour.
  • No Inherent Order (Nominal): When you deal with nominal data, the categories do not follow a certain sequence. This means that the categories have no specific order and each one is equal to the other. 
  • Order with No Exact Measurement (Ordinal): Ordinal data categories have got an important order but the exact differences between categories are not defined. This property introduces hierarchy to the categories but it does not allow for a precise measurement of the gaps between them.
  • Non-Quantifiable: Data that is categorical is implicitly non-quantifiable because it is not numerical. This implies that the only way to work with it in qualitative terms is through comparison rather than computation.

Challenges In Categorical Data

Categorical data holds significant value for analysis, offering insights into various attributes and behaviors. However, it also presents several challenges that can complicate the data analysis process. Understanding these challenges is crucial for effectively managing and interpreting

Categorical data adds complexity to the analysis: Analyzing categorical data requires special statistical methods because they are not numbers or objects that can be placed in a certain order, unlike numerical data.

Data Coding: Organizing categorical data, a method known as data coding, is vital in dealing with qualitative responses. This process may consume a lot of time and tend to have errors which may lead to compromised analysis precision and quality.

Interpretation: Understanding the context and knowing relationships between various categories are essential for making good conclusions from categorical data. Consequently, it’s harder than numerical data analysis for this type of data.

Categorical Data vs Quantitative Data

One thing to know when it comes to data analysis is the difference between categorical and quantitative data. These two types of data serves different purposes and need different analytic methods. This article gives an in-depth comparison which will help you understand these variations in detail.

  • Categorical data: contains discrete groups or categories; best for segmentation and qualitative analysis. Examples include gender, brand preferences, and survey responses.
  • Quantitative Data: This type of data contains numerical values and is applied in quantitative forms of analysis and statistical calculations. Examples include age, income, and sales figures.
