Chapter 3 Data management

The Passion Driven Statistics video calls this section of the course data management. I prefer data wrangling. You are trying to get control of your data so that you and your data can get work done.

Much of the work of anyone who works with quantitative data is data wrangling: creating a dataset for the particular task you have in mind. Work might include subsetting data, filtering data, creating new variables, or making the data easier to understand.

The tools you use will vary based on your goals and your dataset. And your need to wrangle data will likely continue throughout the semester. I’ll note which tools are likely to be useful for each dataset.
