Data science is a "concept to unify statistics, data analysis, informatics, 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, information science, and domain knowledge.

A data scientist is the professional who creates programming code and combines it with statistical knowledge to create insights from data.

 Data science is a multidisciplinary field that involves using a combination of statistical and computational methods to extract insights and knowledge from data. It combines elements of statistics, computer science, and domain-specific knowledge to analyze complex data sets and make data-driven decisions.

Data science involves a range of tasks, including data collection, data preprocessing and cleaning, data analysis and modeling, and data visualization. It also often involves the use of machine learning and artificial intelligence techniques to build predictive models and automate decision-making processes.

Data scientists work in a wide range of industries, including healthcare, finance, retail, and technology, and they use their skills to solve a variety of problems, such as identifying patterns in customer behavior, predicting disease outbreaks, or detecting fraud.
