This chapter addresses data management concerns, focusing less on instrument formatting and more on the process of data entry choices, documentation, hiring, and naming variables. It starts with a discussion of data standards. It details issues related to getting data into an electronic format. These include budgeting money and time, the skills needed for data entry, creating a data entry program, naming variables, formatting, and creating a codebook. The chapter presents guides for cleaning data before and after data entry, tracking project-related data, and archive documentation.
