## Overview

behavioral-data-analysis covers the practical statistics of human performance data: reaction times,
accuracy, choices, and ratings from psychology experiments. It focuses on the preprocessing
decisions that make or break RT analyses (trimming, transformations), the mixed-effects models that
have replaced repeated-measures ANOVA, and robust inference for the skewed, outlier-prone data
behavioral science produces.

## When to use

- Preprocessing RT data: outlier handling, trimming vs transformations, speed-accuracy trade-offs.
- Accuracy/proportion data: logistic mixed models instead of ANOVA on percentages.
- Repeated-measures designs: linear mixed-effects models with crossed random effects.
- Choice data: logistic regression, drift-diffusion modeling basics.
