In turn, these systems generate\u00a0<a href=\"https:\/\/www.datarobot.com\/wiki\/insights\/\">insights<\/a> that analysts and business users can translate into tangible business value. Data science combines multiple fields, including statistics, scientific methods, artificial intelligence (AI), and data analysis, to extract value from data. Those who practice data science are called data scientists, and they combine a range of skills to analyze data collected from the web, smartphones, customers, sensors, and other sources to derive actionable insights.<\/p>\n<p>Data science encompasses preparing data for analysis, including cleansing, aggregating, and manipulating the data to perform advanced data analysis.
