4 Types of Data Nominal, Ordinal, Discrete, Continuous

The data are the different verifiable facts recorded and utilized in the analysis process. Data is present in every industry. Nowadays, data is the lifeblood of business. And so, most firms rely on data insights to establish strategies. It is used to introduce new goods and services, or experiment with new ideas. Today, at least 2.5 quintillion bytes of data are generated each day, according to a report. Types of data are one of the main concepts in Data Science. Let’s discuss the types of data in detail in the blog.

Types of data

It would be best if you played with or experimented with raw or structured data. Regardless of your career, whether you work as a data scientist, researcher.
Because this information is crucial to us, it must be handled and stored correctly. It is essential to understand the different types of data to process these data. Thus provide the desired outcomes.
Quantitative and qualitative data are the two types and It further divided into:

•  Nominal data
• Ordinal data
• Discrete data
• Continuous data

Qualitative Data

A limited number of discrete classes are used in qualitative data. It define the thing under study. It implies that this kind of data cannot be easily measured. And also, cannot be counted using numbers. But must instead be categorized. The gender of a person is a great illustration of this type of data (male, female, or other).

They are audio, visual, or text-based media. Another illustration is a smartphone manufacturer. It lists details such as the phone’s color, category, and more. All this data falls under the category of qualitative data. Under this, there are two subcategories: Nominal data and Ordinal data.

Nominal data

These values are the group that lacks a natural ordering. Let’s use some instances to grasp this better. Since we can’t compare one hue to another, a smartphone’s color can be considered a notional data type.

It is impossible to claim that “Red” is superior to “Blue.” Another aspect of a person’s identity that we cannot separate into male or female. Any mobile phone category, including entry-level, and luxury smartphones, is a nominal data type. ‘Statistics’ nominal data types cannot be quantified or measured. When performing qualitative Research, nominal statistics data are helpful. And so they give people more opportunities to express their opinions.

Ordinal data

These values maintain their class of values while having a natural ordering. When comparing sizes of different clothing , we may organize them by their tags. It has the following hierarchy: small, medium, and Large. A+ is superior to a B grade in the grading method. It is used to mark candidates on an exam, which is an ordinal data type.

These categories assist us in determining which technique to use for a given data type. Translating qualitative input into numerical kinds is necessary. Because they cannot handle these values directly.

One-hot encoding, like binary coding, can be used for nominal data types. And so, with smaller numbers without comparison between the categories. Label encoding, a kind of integer encoding, can be used for ordinal data types.

Difference between Nominal Data and Ordinal Data

Nominal Data	Ordinal Data
Nominal data are not quantifiable and do not have any inherent ordering.	Ordinal data exhibit some sequential order based on their scale positions.
Nominal data includes qualitative and category information.	It argues that ordinal data sits “between” qualitative and quantitative data.
They offer no numeric value, and we cannot execute mathematical operations.	They can assign numbers to ordinal data and give sequences but cannot execute mathematical operations.
Nominal data don’t compare with other nominal data.	Ordinal data compare items by ranking or ordering them.
Examples include eye color, housing preference, gender, hair color, and ethnicity.	Examples include financial situation, amount of client satisfaction, letter grades, etc.

Quantitative Data

This type attempts to quantify things. It does so by considering numerical quantities that lend the object to being countable. Quantitative data categories include the cost of a smartphone. Like any discounts available, the processor speed or RAM of a phone, and many more items.

And also, the crucial point is that a feature can have enduring values. For instance, the price of a smartphone can be any amount between a certain number and another, and it can also be further broken down into fractional quantities. They are divided into the following two types: Discrete and Continuous data.

Discrete data

Integers or whole numbers are the kinds of numerical values. It come under this category. Some examples of the discrete data type are the number of speakers, cameras, and compatible SIM cards. Because the objects in discrete data have a set value, they don’t measure but can only give a number. The value must be entire and expressed as a decimal. Charts, such as bar charts, pie charts, and tally charts, are used to identify discrete data.

Continuous data

Fractional numbers are known as continuous quantities in mathematics. They include the CPU working frequency and the phone’s android version. And also Wi-Fi frequency, core temperature, and others.

Continuous data is broken down into smaller bits. They have any value, unlike discrete data types used in Research, which have a whole and fixed value. Examples of continuous value are temperature and a person’s weight. Graphs are used to display continuous types of statistical data. Thus they can show value fluctuations by the highs and lows of the line throughout time.

Difference between Discrete Data and Continuous Data

Discrete Data	Continuous Data
Discrete data are whole numbers or integers that can be counted and are finite.	Continuous data are quantifiable and expressed as fractions or decimals.
Bar graphs are a typical representation of discrete data.	Continuous data use a histogram.
The values don’t break down into more discrete subdivisions.	The values break down into smaller chunks using subdivisions.
There are gaps between the numbers in discrete data.	A continuous series represents continuous data.
Examples include the total number of students in a class, the days of the week, the size of a shoe, etc.	Examples include the room’s temperature, a person’s weight, an object’s length, etc.

Importance of Types of data

The quality of the information received is the focus of qualitative data. It also aids in understanding consumer behavior. 

This kind of statistical information allows accurate market analysis. Moreover, it adds value to services by incorporating important information. If used wisely, qualitative data from statistics can impact customer happiness.

But, the quantitative data types of numerical values that can be measured. And also it provides answers to questions like “how much,” “how many,” and “how many times.” Statistics’ data kinds have a specific numerical value. As a result, they can assist businesses in evaluating and forecasting future trends.
