Multi-Factor Datasets

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...
