RESEARCH DATA: Formation of teacher expectations: Evidence from a factorial survey experiment manipulating student information
Description
This dataset supports the analysis of a vignette experiment investigating teacher expectations of students (currently in review). It includes structured data and analysis scripts used to study how teachers form expectations based on manipulations of student engagement, characteristics of social group membership and instructional context. This repository includes an R script used for the analysis of the experimental data, along with an accompanying Excel codebook file detailing variable definitions and data structure. Both resources are designed to facilitate reproducibility and provide clear documentation of the study's methodology.

Steps to reproduce
Methods: Data processing, missing data imputation (MICE), and modeling. Robust linear mixed-effects models to analyze relationships. Bootstrapping to derive confidence intervals and diagnostics. Outputs: Statistical metrics like pseudo-R², ICC values, and predicted outcomes for hypothetical cases. Tools: Scripts utilize R libraries such as lme4, mice, ggplot2, robustlmm, and brms.
