What is Data Science?
Data science is an interdisciplinary field that uses scientific methods, processes, algorithms, and systems to extract knowledge and insights from data in various forms, both structured and unstructured, similar to data mining.
In a more recent definition, Pete Warden defines data science as “a set of techniques that can be used to turn raw data into insights and make better decisions.” And he differentiates it from classical statistics by saying “data science includes more exploratory techniques than traditional statistics. Its goals are often focused on discoveries rather than predictions, and it sometimes makes use of techniques that fall outside the usual repertoire of statisticians.”
Moreover, in data science, the emphasis is on extracting data from a variety of sources, cleaning it up, and then using it to generate meaningful conclusions or to build predictive models. Data science combines statistical analysis, machine learning, and programming skills to analyze data, extract insights from it, and turn it into actionable decisions for businesses. The professionals who study and work with such data are called data scientists.
