Why Data Science is important ?

The increased use of the internet globally is generating data at an unprecedented pace. With the pandemic hitting us, we are consuming and producing more data than ever. As a result, we see a significant rise in the demand for more people in the data science industry.

Data Scientists are the backbone of data-intensive companies. The purpose of Data Scientists is to extract, pre-process and analyze data. Industries need data to help them make careful decisions. Data Science churns raw data into meaningful insights. Therefore, industries need data science. A Data Scientist is a wizard who knows how to create magic using data. A skilled Data Scientist will know how to dig out meaningful information with whatever data he comes across.
