What is Data Science and Why It is Trending ?

What is Data Science ?

Data Science is an emerging field in which data is analyzed deeply and useful information or insights are extracted from the data. And later on, predictions can be concluded from that data with the help of some machine learning algorithms. Data Science borrows concepts from other fields like statistics, mathematics and machine learning to perform analysis on data.  It involves steps like data cleaning (removing null or irrelevant data), using stats and mathematics functions to get information from the data, plotting graphs to show insights of data and then finally applying some algorithm to predict from that data.
