This chapter will introduce a multi-factor dataset and explain how to use exploratory data analysis techniques to analyze this data. In previous chapters, we focused on univariate and multivariate datasets. Univariate and multivariate datasets represent two patterns to statistical analysis. Univariate analysis involves the analysis of a single variable, while multivariate analysis involves the analysis of two or more variables. Most multivariate analysis involves implementation of dependent variable and multiple independent variables. Multiple factor datasets simultaneously analyze several tables of variables to obtain results. In this chapter, we will first learn to read and tidy the data, after which we will learn to map and understand the underlying structure of the dataset and identify the important variables. We will then create a list of outliers or...

Overview of this book
Hands-On Exploratory Data Analysis with R will help you build a strong foundation in data analysis and get well-versed with elementary ways to analyze data. You will learn how to understand your data and summarize its characteristics. You'll also study the structure of your data, and you'll explore graphical and numerical techniques using the R language.
This book covers the entire exploratory data analysis (EDA) process—data collection, generating statistics, distribution, and invalidating the hypothesis. As you progress through the book, you will set up a data analysis environment with tools such as ggplot2, knitr, and R Markdown, using DOE Scatter Plot and SML2010 for multifactor, optimization, and regression data problems.
By the end of this book, you will be able to successfully carry out a preliminary investigation on any dataset, uncover hidden insights, and present your results in a business context.
