What is data science
Data science is a field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from structured and unstructured data. It is a multidisciplinary field that combines domain expertise, programming skills, and knowledge of mathematics and statistics to extract actionable insights from data. Data scientists are responsible for collecting, storing, processing, and analyzing large sets of data, and using their findings to make data-driven decisions. Some of the tasks that data scientists might perform include building statistical models, creating machine learning algorithms, and visualizing data. Data science is a growing field that is expected to have a significant impact on many industries, including finance, healthcare, retail, and transportation.
