Teaching Assistant, College of Information, University of Maryland, 2026
Teaching assistant for Dr. Sarah Lee (ongoing).
- Lead lab sessions in R and RStudio, guiding students through hands-on statistical experiments.
- Lead discussions of core statistical topics.
- Created The Cookie Series, interactive browser demos that help students learn and review sampling distributions, confidence intervals, and hypothesis testing. All the data are simulated, so students can compare every method against the true answer.
The Cookie Series: interactive demos
🍪 The Cookie Question How many cookies does a Terp eat in a semester? Watch the sampling distribution of x̄ get built three ways (repeated sampling, the bootstrap, and the CLT formula) and see when a confidence interval catches the true mean. Open the demo → ⚖️ The Cookie Claim: Reject or Not? Put a fictional cookie-counter manager's claim on trial. Hypothesis testing as a courtroom: H₀ and Hₐ, z-scores, p-values, Type I and II errors, and how tests and confidence intervals agree. Open the lab →
