Data Types Every Aspiring Data Scientist Should Know

Data is the engine and a necessary component for data-driven firms to gain useful insights and make business choices. Data that is both structured and unstructured is used extensively in data science techniques. Before you begin working with it, it is essential to understand the different data types utilized in data science.

But first, let’s get to the basics.


What is data?

Data is a term that encompasses many sorts of information that are often formatted in a specific way. Programs and data are the two main divisions of any software. Programs are collections of instructions used to change data; we already know what data is.


We use data scienceto simplify working with data. Data science is defined as a field that brings together mathematical expertise, programming know-how, domain knowledge, scientific methods, algorithms, processes, and systems to extract useful information and insights from both structured and unstructured data, then apply the information derived from that data to a variety of purposes and domains.

What is a data type?

The characteristic of a value that establishes its domain is its data type. An essential characteristic that informs a computer or system of the value of a particular piece of data is the data type. A data type must be thoroughly understood and analyzed to make sure the data has been collected in the desired format, event properties have been correctly defined, and the data value is as expected. Both classifications of data and the kinds of data used in data science are the main topics of the essay. You may concentrate on effectively using data with the assistance of this segmentation.


Data Types and Uses


Categorical data

A grouping of data is referred to as "categorical data." Measuring on a categorical scale entails monitoring an experiment's outcome and designating it to one of a limited number of classes. Information tables are typically used in the analysis of categorical data. To better illustrate, I'll use a business as an example: If a company decides to divide its employee population based on its portfolio, the resulting data will be categorical, and the employees will be divided into groups according to their departments, teams, educational backgrounds, gender, place of residence, etc.

For example, during a study, 20 people were asked to name the color of their eyes and hair.


Numeric Data

We state that everything can be quantified if it can be measured and counted. Quantitative data is what it sounds like—tangible information gathered through a research approach. In statistics, numerical or quantitative data types quantify phenomena by accounting for numerical values, making the data countable. Quantitative data that can be measured and confirmed serves as the foundation for statistical analysis. These data provide us with knowledge regarding quantities or information that can be measured and expressed as a numerical value.


For example, the number of persons who visited the cinema over a month. 


Conclusion :

As a data scientist, you should be able to apply data types because understanding it is essential to driving decision-making processes that rely on it. A fundamental understanding of data types will assist you in:



Handling data properly


Understand what you can compute using data.


What kind of data can you use to achieve your goals?


Describe or show the data


Data science job roles are likely to get more specific, leading to specialization in the field.
