Study Notes
Types of Analytics
- Decision analytics: supports decision-making with visual analytics that reflect reasoning
- Descriptive analytics: provides insight from historical data with reporting, scorecards, clustering, etc.
- Predictive analytics: employs predictive modeling using statistical and machine learning techniques
- Prescriptive analytics: recommends decisions using optimization, simulation, etc.
Data Science, Social Science, and Computational Social Science
- Data science is used in government policies, people's mandates in elections, and hiring strategies in the private sector
- Information science involves understanding information in different contexts and circumstances related to data creation, generation, and sharing
Information vs. Data
- Data is something raw and meaningless, while information is data with meaning and purpose
- An example of data vs. information is the number "480,000" being a data point, but when explained as the number of deaths per year in the USA from cigarette smoking, it becomes information
Data Science and Statistics
- Data scientists should have at least three basic skills: knowledge of statistics, computer science skills, and data visualization skills
- The difference between data science and statistics lies in the invention and advancements of modern computers
Data Science and Computer Science
- Data science and computer science overlap and are mutually supportive
- Computer science algorithms and techniques, such as machine learning and data visualization, have contributed to the data science discipline
Data Science and Engineering
- Engineering in various fields has created demand for data scientists and data science methods
- Data science has benefitted from new software and hardware developed via engineering, such as CPU and GPU
Data Science and Business Analytics
- Business analytics (BA) refers to the skills, technologies, and practices for continuous iterative exploration and investigation of past and current business performance
- BA focuses on developing new perspectives and making sense of performance based on data and statistics
- There are four types of analytics: descriptive, predictive, prescriptive, and decision analytics
Data Science Definition and Importance
- Data science is a multidisciplinary blend of data inference, algorithm development, and technology to solve analytically complex problems
- Data science is a field of study and practice that involves the collection, storage, and processing of data to derive important insights and make better, fact-based decisions
- The "3V model" describes the characteristics of big data: velocity, volume, and variety
- Data science is important now because it is virtually everywhere, and its applications are numerous, including finance, public policy, politics, healthcare, urban planning, education, and libraries
