Data Cleaning

Lesson Prerequisites

This lesson assumes that you have basic knowledge of Stata syntax and writing code in .do files (Intro to Stata, Stata Best Practices), an understanding of the sources of errors in data collection (Collecting High-Quality Data, Questionnaire Design), and familiarity with the pros & cons of digital data collection (e.g. the first section on mobile data collection in the SurveyCTO lesson; knowledge of SurveyCTO itself is not necessary for this lesson).
