What is the definition of data?
What is the definition of data?
- Data are raw symbols that represent the properties of objects and events and in this sense data has no meaning of itself, it simply exists (correct)
- Data are processed symbols that hold meaning and context
- Data are information that leads to decision making
- Data are symbols that are processed to derive meaning and context
What is the difference between data and information?
What is the difference between data and information?
- Data is processed, while information is raw
- Data are raw symbols, while information includes meaning and context (correct)
- Data holds no meaning, while information leads to decision making
- Data is qualitative, while information is quantitative

Study Notes
Definition of Data
- Data refers to raw facts and figures that can be processed to derive meaning.
Difference Between Data and Information
- Data consists of unprocessed elements, while information is the result of processing and organizing data to provide context and significance.
Components of Knowledge
- Knowledge consists of integrated information that has been comprehended and interpreted, leading to insights and understanding.
Objective of Introductory Module on Data Science
- The main objective is to provide foundational knowledge about data, its processing, and the principles of data science.
Emphasis on Manipulating Data
- The module stresses the importance of effective data manipulation skills to analyze and derive valuable insights from datasets.
Step 4 of the Data Science Process
- Step 4 typically involves modeling, where predictive models are created to analyze data further.
Non-Data Science Tool
- Identifiable non-data science tools are specifically determined within the course content, distinguishing them from standard data science tools.
Definition of Data Science
- Data science is defined as the interdisciplinary field that uses scientific methods, processes, algorithms, and systems to extract knowledge or insights from structured and unstructured data.
Task of Performing Data Science
- Laura, Igual, and Seguí Santi describe the task of performing data science as a combination of statistical analysis and predictive modeling to solve complex problems.
Extraction of Information from Data
- The term used for extracting information from data is "data mining," which encompasses various methods, processes, and algorithms from business, statistics, and computer science.
