Study Notes

Data Science

Data science is an interdisciplinary field that combines statistics, scientific computing, and scientific methods to extract knowledge and insights from structured and unstructured data.
It integrates domain knowledge from various application domains, such as natural sciences, information technology, and medicine.

Characteristics of Data Science

Data science is multifaceted and can be described as a science, research paradigm, research method, discipline, workflow, and profession.
It uses techniques and theories drawn from mathematics, statistics, computer science, information science, and domain knowledge.
Data science is distinct from computer science and information science.

Definition of a Data Scientist

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

Foundations of Data Science

Data science involves preparing data for analysis, formulating data science problems, analyzing data, developing data-driven solutions, and presenting findings to inform high-level decisions.
It incorporates skills from computer science, statistics, information science, mathematics, data visualization, and communication.

Relationship to Statistics

Data science is not a new field, but rather an extension of statistics, focusing on problems and techniques unique to digital data.
Data science deals with both quantitative and qualitative data, emphasizing prediction and action.

Etymology of Data Science

The term "data analysis" was first used by John Tukey in 1962, which resembles modern data science.
The term "data science" was first used by C. F. Jeff Wu in 1985 as an alternative name for statistics.
