What is Data Science?

Let’s begin by explaining what data science is. Also, let’s learn why it’s so important today.

Simply put, data science is the study of data. First, the data is chaotic and messy. Data science processes develop meaning from that data. The field combines different principles from disciplines like:

– mathematics
– statistics
artificial intelligence
– computer engineering


There are many sources of data. We collect and store it. This happens every second of every day.

This stored-but-messy data would only have a little use if it weren’t for data science. Here’s the good news. Data science chooses and changes raw data into facts. Then, businesses can use it to make good decisions.

Data science is currently applied in every industry you can think of. That includes marketing, economy, law, health, IT, and many more.

What Do Data Scientists Do?

Data scientists are the people in charge of the processes we’ve just described. They are analytical data professionals. They have a number of different tasks and duties.


Their primary assignments include:
– deciding what questions need to be answered
– choosing which data to analyze
– converting and adjusting that data
– analyzing it


Data scientists first finish the analysis. Then, they need to interpret the result. The result will answer the initial question. Finally, this will help them reach a solid conclusion.


Based on the analysis they carry out, data scientists then get to:
– give ideas and tips to different teams in a company
– create predictions and suggest the best business models
– decide how to improve a product or service
– notice potential problems


Data scientists are vital for every business. It doesn’t matter how big it is or what industry it’s in.
