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.
