5 Best Data Science Tutorials for beginners in localdown time

India is the second-most populous country in the world with a population of 133.92 Crores. With such a large population comes an equally humungous amount of data. Thus, managing, structuring, storing and studying the data is a tough challenge! Well, Data Science is exactly what we need here.

We know the definition of science from our elementary school. Anything related to "cause" and "effect" is called science. In broader terms, the study of nature, behavior, outcomes, and effects of any activity or entity is science. When we take "Data" as the central focus of our study, then Data Science comes into the picture.
When we study Data, we analyze the trends in data. We try to draw patterns in the behavior of the statistics(data). People who are engaged in the domain of Data Science are called Data Scientists.

In a software development agency, Data Scientists study the patterns of data and based on the conclusions made by those patterns they tend to predict the further possible behavior of the entity. It sounds interesting but is equally challenging at the same time.
Considering the above features, it is, undoubtedly, worth learning Data Science. Lucrative compensation and exponential growth are the factors that make Data Science a perfect career option!

Thus, we provide you a highly curated list of Data Science courses that you can consider taking to strengthen your career.
