# Survey Data Processing

A skill for cleaning, recoding, and preparing survey response data for statistical analysis. Covers handling common survey data issues such as incomplete responses, attention check failures, reverse-coded items, scale construction, open-ended response coding, and export to analysis-ready formats compatible with SPSS, Stata, and R.
