Data types are critical aspect of statistical analysis, which needs to be understood to correctly use statistical techniques to your data. There room 2 main species of data, namely; categorical data and also numerical data.

You are watching: Is an id number categorical or quantitative

As one individual who works with categorical data and numerical data, that is important to properly know the difference and similarities in between the 2 data types. This will make it simple for friend to properly collect, use, and also analyze them.

The importance of expertise the different data varieties in statistics can not be overemphasized. Therefore, in this article, we will be researching at the two main varieties of data- consisting of their similarities and also differences.

What is Categorical Data?

Categorical data is a kind of data that have the right to be save on computer into teams or categories v the help of name or labels. This grouping is typically made follow to the data characteristics and also similarities that these characteristics through a method known together matching.

Also well-known as qualitative data, each facet of a categorical dataset deserve to be put in just one category according come its qualities, whereby each of the category is support exclusive. For example, gender is a categorical data because it have the right to be categorized right into male and female follow to part unique qualities possessed by each gender.

There room 2 main varieties of categorical data, namely; in the name data and ordinal data.

Nominal data

This is the data kind of categorical data the names or labels. Sometimes referred to as naming data, it has characteristics comparable to that of a noun.

E. G. Name of a person, gender, school graduates from, etc.


Ordinal data

This kind of categorical data includes aspects that are ranked, notified or have actually a rating range attached. One deserve to count and also order, in the name data, yet it have the right to not be measured.

For example, intend a group of customers were asked come taste the arrays of a restaurant"s new menu ~ above a rating scale of 1 to 5—with every level top top the rating scale representing strong dislike, dislike, neutral, like, strong like. In this case, a rating of 5 indicates an ext enjoyment than a rating the 4, making such data ordinal.

What is number Data?

Numerical data is a type of data that is express in terms of numbers quite than organic language descriptions. Comparable to its name, numerical, it can only be gathered in number form. Additionally known as quantitative data, this number data type can be provided as a kind of measurement, such together a person’s height, weight, IQ, etc.

It can likewise be offered to bring out arithmetic operations like addition, subtraction, multiplication, and also division.

There space 2 types of numerical data, namely; discrete data and consistent data.

Discrete Data:

Discrete data is a kind of numerical data with countable elements. I.e they have a one to one mapping with organic numbers. A discrete data have the right to either be countably finite or countably infinite. Some general instances of discrete data are; age, number of students in a class, number of candidates in an election, etc.

A countably limited data can be counted native the beginning to the end, when a countably boundless data cannot be totally counted due to the fact that it tends to infinity.

For example, the bags of rice in a store are countably finite while the grains of rice in a bag is countably infinite

Continuous Data

Continuous is a number data form with uncountable elements. They are represented as a collection of intervals ~ above a actual number heat . Comparable to discrete data, continuous data can likewise be one of two people finite or infinite

An uncountable limited data collection has an end, while an uncountable boundless data collection tends come infinity.

Continuous data deserve to be further separated into term data and also ratio data. Some instances of continuous data are; college student CGPA, height, etc.

15 crucial Differences between Categorical & number Data


Categorical data is a kind of data that is provided to team information with comparable characteristics while numerical data is a form of data the expresses information in the type of numbers. It combine numeric worths to depict relevant information while categorical data offers a descriptive approach to to express information

We deserve to see the the 2 definitions over are different. Therefore, categorical data and numerical data perform not mean the exact same thing.

Other Names

Categorical data is likewise called qualitative data while number data is additionally called quantitative data. This is because categorical data is provided to qualified information prior to classifying them follow to their similarities.

Numerical data is used to express quantitative values and also can additionally perform arithmetic operations i m sorry is a quantitative characteristic.

Both numerical and categorical data have actually other names the depict your meaning. Yet the names are but different from every other.


Categorical data instances include an individual biodata information—full name, gender, call number, etc. Number data examples encompass CGPA calculator, interval sale, etc.

The examples below are instances of both categorical data and also numerical data respectively.

A CGPA calculator that asks students to input their grades in every course, and the number of units to calculation their CGPA.

For example, 1. Above the categorical data come be built up is nominal and is gathered using one open-ended question. Example 2. Is a numerical data type.

The contents suggestion right here (See how you can develop a CGPA calculator making use of chrischona2015.orgus.)


Categorical data is separated into two types, namely; nominal and also ordinal data while numerical data is categorised right into discrete and constant data. Constant data is currently further separated into interval data and ratio data.

Although they space both of 2 types, this data types are not similar.

Data Characteristics

The characteristics of categorical data include; lack of a standardized order scale, organic language description, take away numeric values with qualitative properties, and also visualized utilizing bar chart and pie chart.

Numerical data, top top the various other hand, has a standardized order scale, numerical description, takes numeric values with numerical properties, and also visualized using bar charts, pie charts, scatter plots, etc.

User-centred Design

Numerical data collection an approach is more user-centred 보다 categorical data. Many respondents do not desire to invest a many time pour it until it is full out forms or surveys i m sorry is why questionnaires provided to collection numerical data has actually a lower abandonment rate contrasted to that of categorical data.

This is because categorical data is mostly gathered using open-ended questions.

Data collection Methods

Categorical data can be built up through various methods, which might differ native categorical data types. For instance, in the name data is mostly built up using open-ended inquiries while ordinal data is mostly gathered using multiple-choice questions.

Numerical data, on the other hand, is mostly built up through multiple-choice questions. Us observe that it is mostly collected using open-ended questions whenever there is a need for calculation.

Data repertoire Tools

Data collectors and also researchers collection numerical data utilizing questionnaires, surveys, interviews, emphasis groups and also observations. Categorical data is accumulated using questionnaires, surveys, and also interviews.

Data arsenal is commonly straightforward with categorical data and also hence, walk not need technical tools favor numerical data. For example, numerical data that a participant"s score in different sections of one IQ test might be forced to calculate the participant"s IQ.

When collected using virtual forms, this might require part technical enhancements to the form, unequal categorical data i m sorry is simple.

Analysis & Interpretation

There are 2 methods of performing number data analysis, namely; descriptive and inferential statistics. Some examples of these 2 approaches include; procedures of central tendency, turf analysis, text analysis, conjoint analysis, trend analysis, etc.

There are also 2 techniques of assessing categorical data, namely; median and mode. In some cases, we watch that ordinal data Is analyzed making use of univariate statistics, bivariate statistics, regression analysis, etc. I m sorry is supplied as an different to calculating mean and standard deviation.


Numerical data is mostly used for calculation problems in statistics as result of its ability to perform arithmetic operations. For example, when designing a CGPA calculator, one may need come include commands that allow for the addition, subtraction, division, and also multiplication.

Categorical data, on the other hand, is greatly used because that performing research study that requires the use of respondent"s personal information, opinion, etc. The is generally used in service research.


Numerical data is compatible with many statistical evaluation methods and also as such renders it the many used amongst researchers. Categorical data, ~ above the other hand, does no support most statistical analysis methods.

There are choices to some of the statistical evaluation methods not supported by categorical data. However, they can not provide results that space as specific as the original.


Numerical data analysis is greatly performed in a standardization or controlled environment, which might hinder a proper investigation. This is since natural determinants that may affect the results have been eliminated, resulting in the results not come be completely accurate.

Numerical data arsenal is also strictly based on the researcher"s point of view, limiting the respondent"s influence on the result. This is not the case with categorical data.

Nominal data captures human emotions to an extent through open-ended questions. However, the setback through this is that the researcher may sometimes have to attend to irrelevant data.



Numerical data is compatible with many statistical techniques of data analysis, however categorical data is incompatible through the majority of these methods. Therefore, hindering some sort of research study when dealing with categorical data.

More reasons why most researchers favor to usage categorical data.


Categorical data have the right to be visualized using only a bar chart and also pie chart. The bar graph is provided when measuring for frequency (or mode) while the pie chart is offered when dealing with percentages. Number data, on the other hand,d have the right to not just be visualized using bar charts and also pie charts, yet it can also be visualized using scatter plots.


Categorical data can be taken into consideration as unstructured or semi-structured data. It is loosely formatted v very tiny to no structure, and also as such cannot be gathered and analyzed using conventional methods.

Although there room some approaches of structuring categorical data, the is quiet quite daunting to make appropriate sense that it. This technique is had to do with indexing, i m sorry is what search engines prefer Google, Bing, and also Yahoo use.

Numerical data, top top the various other hand, is taken into consideration as structured data. The is formatted in such a means that it deserve to be quickly organized and also searchable within relational databases. E.g. Numbers and values uncovered in spreadsheets.

Similarities in between Categorical & number Data

Ordinal Data

Although proven to be an ext inclined come categorical data, ordinal data can be classified as both categorical and also numerical data. In some texts, ordinal data is defined as one intersection between numerical data and categorical data and also is because of this classified together both.


Numerical and also categorical data have the right to not be provided for research and also statistical analysis. Lock might, however, be supplied through different approaches, yet will provide the very same result.

Researchers sometimes check out both categorical and numerical data as soon as investigating come explore different paths come a solution. Because that example, an organization might decide to investigate which type of data collection an approach will help to reduce the abandonment rate by trying out the 2 methods.

Hence, the organization may ask this 2 concerns to investigate the solution rate.

Question 1:

What execute you think about our product? ____

Question 2

Rate ours product on a range of 1 to 5.

12345Numerical Value

Both numerical and also categorical data have the right to take numerical values. Categorical data have the right to take values like identification number, postal code, phone number, etc. The only difference is that arithmetic operations can not be carry out on the values taken by categorical data.

Collection tools

Numerical and also categorical data can both be built up through surveys, questionnaires, and also interviews.
