Data Science What is Data Science?? Data Science is a blend of scientific methods, processes, algorithms and systems to extract knowledge and insights from many structural and unstructured data. It provides meaningful information based on large amounts of complex data or big data. It is related to data mining, machine learning and big data. It is a concept to unify statistics, data analysis and their related methods in order to understand and analyse actual phenomena with data. It uses techniques and theories drawn from many fields within the context of mathematics, statistics, computer science, domain knowledge and information science.
Purpose of Data Science The principal purpose of Data Science is to find patterns within data. It uses various statistical techniques to analyze and draw insights from the data. From data extraction, wrangling and pre-processing, a Data Scientist must scrutinize the data thoroughly. Then, he has the responsibility of making predictions from the data. The goal of a Data Scientist is to derive conclusions from the data. Through these conclusions, he is able to assist companies in making smarter business decisions.
