Study Notes
Defining Data Science
- Data Science is a field that combines concepts from statistics, computer science, and domain-specific knowledge to extract insights from data.
The Hype Around Big Data and Data Science
- The hype around Big Data and Data Science has led to a surge in interest and investment in the field.
- It's essential to get past the hype and understand the real value of Data Science.
Why Now?
- The current era of Data Science is driven by the increasing availability of data and the need to make sense of it.
- Datafication, the process of turning aspects of life into data, has led to a massive amount of data being generated.
Current Landscape of Perspectives
- Data Science is a multidisciplinary field that draws from various perspectives, including statistics, computer science, and domain-specific knowledge.
A Data Science Profile
- A Data Scientist should have a strong foundation in statistics, programming, and domain-specific knowledge.
- A Data Scientist should also possess skills such as data wrangling, data visualization, and communication.
Skill Sets for a Data Scientist
- Statistical Inference: drawing conclusions about a population from a sample.
- Programming skills, particularly in languages like R and Python.
- Domain-specific knowledge to provide context to the data analysis.
Foundations of Statistics
- Statistical Inference: the process of making conclusions about a population from a sample.
- Populations and Samples: understanding the difference between the two and how to work with them.
Big Data and New Kinds of Data
- Big Data refers to the large and complex datasets that traditional data processing tools cannot handle.
- New kinds of data, such as text, image, and audio data, require specialized techniques to analyze.
Modelling and Statistical Modeling
- Modelling involves using mathematical and statistical techniques to describe and analyze data.
- Statistical modeling involves using probability distributions to model and analyze data.
Probability Distributions
- Probability distributions, such as the Normal Distribution and the Binomial Distribution, are used to model and analyze data.
Fitting a Model
- Fitting a model involves using data to estimate the parameters of a probability distribution.
Introduction to R
- R is a popular programming language and environment for statistical computing and graphics.
- R is widely used in Data Science for data analysis, visualization, and modeling.
