Preparing Data for Analysis

Once we have gathered the raw data that we want to include in our statistical analyses, we generally need to clean it up so that it can be merged into a single data set that we can easily use for statistical analysis. In this chapter we will learn how to create the data gathering and merging files we saw in the last chapter. This includes recoding and transforming variables in the data set so that the data sets can be easily merged. This will also be useful information in later chapters as well. If you are very familiar with data transformations in R, you may want to skip to the next chapter.
