What Is Data Science - Definition, Courses, FAQs

Data science is a very broad term, and to define what is data science, you have to start somewhere. There are many different sub-disciplines within data science that range from computer science and engineering to biology and statistics. Data scientists are professionals who are involved in the collection, analysis, modeling, visualization and interpretation of data. Some people may argue that data doesn't need explaining or that it shouldn't be explained because the truth is truth.

As this idea has been around for a long time, many professionals haven’t really grasped the concept behind data science. Data science is growing at an exponential rate and it’s important to keep up with new developments in this field. One way to do this is by taking a data science certification course. In this article, we will try to explain in detail what is data science and how you can get started learning it through various online courses and certifications.

Is Data Science For You?

Some people may question whether or not they should learn data science because they don’t know how to explain what is data science. However, this is a common misconception because the truth is truth and ignorance really doesn’t exist. Data science is just the use of technology to process information in a systematic way. You wouldn't say that math doesn't need explaining because math just numbers adding up or that cooking isn't important because anyone can make food. Data science is no different and trying to explain it further would only make it more complicated than needed. If you're still not convinced then consider this: Companies have been collecting data for years but only recently has there been an influx of interest.

Data Science Certification Courses

The first step in learning data science is to get certified. There are many different online diploma courses, online degree courses or data science certification courses that you can get opt for. However, the most popular one is the Data Science Professional (DS) certification. The DS course teaches students how to understand data and how to analyze datasets. This data science certification course helps prepare graduates for work in a variety of fields including industries with huge amounts of data and analytics like healthcare and finance. The DS certification is more than just a piece of paper though, as it also includes a live exam that covers topics like statistics, regression, machine learning and programming on R or Python.

Apart from this, there are many online courses available for free, but if you want to learn from professionals then the cost will be a little more expensive. Data science certification courses provide you with hands-on experiences that allow you to get your feet wet in the industry before deciding whether or not you want to pursue a career in data science.
