What is Data Science??

As the definition says, "Data science is an interdisciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from noisy, structured and unstructured data, and apply knowledge and actionable insights from data across a broad range of application domains". In this article we will discuss more about Machine Learning. So, suppose we have gone to a university just to do some research on how students of that particular university are getting marks according to the number of hours they study. NOTE: This is a hypothetical data not a real world data. This data says that the student who is studying 3 hours is getting 30 marks and the students who is studying 8 hours is getting 80 marks.
