What Is Data Science? The Basics of Data Science

Data Science is a big field. It’s growing exponentially with the increase in data collection and computing power. The goal of Data Science is to extract insights from data that can be used for business intelligence or predictive analytics purposes. Data Scientists are often employed by IT giants such as Microsoft, Google, IBM, and so on. They use advanced techniques such as machine learning and statistical modeling to create new products or solve complex problems for their employers.

What is data science?

Data science is a field that employs a wide range of knowledge and skills from computer science, mathematics, statistics, and the social sciences. Data science has been around for a long time but it’s only been in the last few years that data science has exploded as a field. Data Science is an emerging field with many different jobs within it.

The Basics of Data Science

Data Science is quickly becoming an essential skill across all industries. The goal of Data Science is to extract insights from data that can be used for business intelligence or predictive analytics purposes.

Here are some ways you might use data science in your own life:

  • To analyze your online habits
  • To predict what you will buy next
  • To recommend potential jobs to you

How do Data Scientists work?

Data Science is a broad field and has many different applications. One of the most common ways to employ data science is through data mining, which includes the extraction of information from large amounts of data. Data Scientists use techniques such as clustering and association rule mining to find specific types of patterns in large datasets.


Data scientists also use their skills to analyze and classify data. They often work with unstructured data such as text or images, and they’ll collect this data from various sources such as social media platforms or databases. From here, the Data Scientist will analyze the data and identify what types of insights they can derive from it using statistics and machine learning algorithms.

How can you use data science in your life?

Data science can be used for a wide range of purposes. Let’s look at some ways you might use data science in your life.

  • If you are an entrepreneur or business owner, you could use it to create different products or solve problems.
  • If you are working in the medical field, data science could help you make more informed decisions about patients’ health care.
  • If you love architecture, data science can help you create better buildings with the latest design trends and technologies.
  • If you work in retail or marketing, data science can help predict buying trends and improve customer experience to increase sales.
  • If you’re curious about what other people think, social media is a great way to understand what people are thinking by analyzing their posts and interactions on the platform.

Data Robot

Data Robot uses artificial intelligence to automate data analysis. Using drag-and-drop technology, Data Robot users can build their own models without writing any code. This frees up valuable time for data scientists to pursue creative endeavors or use their expertise elsewhere.


Microsoft Azure provides an easy solution for storing large datasets which are necessary for these types of projects. Microsoft’s cognitive services are providing more tools to make it easier for Data Science professionals to analyze volumes of data quickly – whether it be image recognition through Project Oxford or Natural Language Processing (NLP) through Bing search engine.

Why Data Science is Important?

Data Science can be used in many different ways, but it essentially boils down to using data to make smarter decisions. For example, if you’re a manager at a corporation and want to start a new marketing campaign, you would need the right data about your target audience before you could make an informed decision about whether or not it’s worth continuing with your plan. The same goes for any company: You need information about your customer base before you can come up with strategies that will work best for them. Or maybe you’re not a manager-maybe you work in finance and trying to find investments that will keep your pension fund solvent for years to come.


In this case, the data science skills needed would be more mathematical than managerial, but they’d still allow you to gain key insights into how your money will perform in the future so that when investing time and money into stocks and bonds, you’re making better choices than just guessing what might happen in the future.

What kinds of problems do data scientists solve?

Data scientists work with different data types and problems. Here are some ways you might use data science in your own life:

  • A company, such as a bank, might employ a data scientist to develop an algorithm that helps predict which customers would be most likely to switch companies.
  • An e-commerce company could hire a data scientist to develop a system that predicts product sales trends.
  • A manufacturing company might have a data scientist who develops models that predict when items will need maintenance or replacement.
  • A political campaign might have a data scientist on staff who builds predictive models of voting behavior.

It’s important for Data Scientists to know how their models will be used so they can best serve their employer. A model built by a Data Scientist for the purpose of predicting which customers would most likely switch banks may not be appropriate for predicting which customers would most likely buy a new TV. Taking into account the end goal of the Data Scientist’s project is critical for success.

Basic libraries used in Data Science

The following are the libraries that are most commonly used in Data Science.

  • Python is a popular programming language that can be used for data analysis.
  • Pandas is another popular library that provides data structures and tools for data manipulation.
  • Matplotlib is a library for plotting charts.
  • Scikit-learn is a machine learning library for Python.
  • Potables provides efficient solutions to read, write, and query tables of data.
  • NumPy adds fast processing of large arrays and matrices to Python.

Data Science is a relatively new field that has the potential to change the world. The basics of Data Science involve using tools and techniques from computer programming, statistics, and data analysis to extract insights from data sets. It’s a growing field with a lot of potential for innovation. Data Scientists use current tools and techniques to extract insights from large datasets. In order to do this, Data Scientists need to be well-versed in a number of topics, including computer programming, statistics, and data analysis.
