Overview of this book

Data mining is the first step to understanding data and making sense of heaps of data. Properly mined data forms the basis of all data analysis and computing performed on it. This learning path will take you from the very basics of data mining to advanced data mining techniques, and will end up with a specialized branch of data mining—social media mining. You will learn how to manipulate data with R using code snippets and how to mine frequent patterns, association, and correlation while working with R programs. You will discover how to write code for various predication models, stream data, and time-series data. You will also be introduced to solutions written in R based on R Hadoop projects. Now that you are comfortable with data mining with R, you will move on to implementing your knowledge with the help of end-to-end data mining projects. You will learn how to apply different mining concepts to various statistical and data applications in a wide range of fields. At this stage, you will be able to complete complex data mining cases and handle any issues you might encounter during projects. After this, you will gain hands-on experience of generating insights from social media data. You will get detailed instructions on how to obtain, process, and analyze a variety of socially-generated data while providing a theoretical background to accurately interpret your findings. You will be shown R code and examples of data that can be used as a springboard as you get the chance to undertake your own analyses of business, social, or political data. This Learning Path combines some of the best that Packt has to offer in one complete, curated package. It includes content from the following Packt products: ? Learning Data Mining with R by Bater Makhabel ? R Data Mining Blueprints by Pradeepta Mishra ? Social Media Mining with R by Nathan Danneman and Richard Heimann

Chapter 2. Exploratory Data Analysis with Automobile Data

Exploratory data analysis is an integral part of data mining. It involves numerical as well as graphical representation of variables in a dataset for easy understanding and quick conclusion about a dataset. It is important to get an understanding about the dataset, type of variables considered for analysis, association between various variables, and so on. Creating cross tabulations to understand the relationship between categorical variables and performing classical statistical tests on the data to verify various different hypotheses about the data can be tested out.

You will now get an understanding about the following things:

  • How to use basic statistics to know properties of a single and multiple variables
  • How to calculate correlation and association between two or more variables
  • Performing multivariate data analysis
  • Statistical properties of various probability functions for any dataset
  • Applying statistical tests...
