A data-driven externship with the Center for Improving Youth Justice that analyzed administrative and incident records to surface correlations in juvenile facility outcomes.
The project analyzed CIYJ's multi-decade dataset of youth and staff surveys, incident reports, demographics, and outcomes to test common assumptions about juvenile facility operations. The work defined analytic approaches, measured which variables correlated with adverse incidents, and produced cleaned, documented data ready for further modelling.
I reviewed the dataset and established an analytic approach, documenting the limits of correlational methods and the practical role of the analysis within the project's scope.
