Sep. 2024Amherst, Massachusetts, United States▪ Performed psychometric analysis on K–12 survey data (1,200+ student and teacher responses across six schools) to evaluate perceptions of library engagement, instructional support, and research resource accessibility. ▪ Preprocessed multi-tab Excel survey data using R (tidyverse, readxl, dplyr)—standardized variable formats, merged datasets across schools, and implemented listwise deletion to address missingness. ▪ Executed EFA and PCA to identify latent constructs, followed by reliability and validity diagnostics using Cronbach’s Alpha, Guttman's Lambda-6, KMO measure, and Bartlett’s test of sphericity. ▪ Developed visual analytics (e.g., ggplot2 histograms, scree plots, correlation heatmaps) and authored a reproducible analysis pipeline in R Markdown along with a technical brief for reporting and stakeholder presentation.
