UVA STAT 2120: Introduction to Statistical Analysis
STAT 2120 is UVA's introductory statistics workhorse — probability foundations, sampling distributions, confidence intervals, hypothesis testing, and regression — required or recommended across economics, pre-comm, and quantitative social science tracks, typically with software-based work in discussion sections.

Build my STAT 2120 study planWhat makes it hard
The course is cumulative with a predictable failure arc: descriptive statistics feels easy, probability gets skimmed, and then inference arrives assuming both fluently. Exams emphasize choosing the right procedure and interpreting results in context — the exact skills formula-memorizers don't build — and the regression material at the end assumes everything before it.

The STAT 2120 study guide
How to study for UVA STAT 2120, step by step.
- 1
Take probability seriously while it's cheap to
The STAT 2120 failure arc runs through a skimmed probability unit. Inference assumes it fluently — give the probability weeks full effort while the material still feels manageable.
- 2
Practice scenario-to-procedure matching
Given a described study, decide which interval or test applies and why, before computing anything. Exams grade that selection step heavily, and it's exactly what formula-memorizers skip.
- 3
End every problem with a sentence
One plain-English interpretation in context — what does this interval or p-value actually say? That's the format exam questions reward, and the habit cements the concepts.
- 4
Do the software work early in the week
Discussion-section assignments surface confusion while there's still time to fix it. Deadline-night software sessions convert fixable gaps into permanent ones.
- 5
Review cumulatively every week
Regression at the end assumes intervals, tests, and probability all at once. Folding earlier-unit questions into each week's study keeps nothing cold when the course needs everything simultaneously.

How Fennie helps with STAT 2120
Fennie's Daily Plans hold STAT 2120's cumulative line — probability locked down before inference assumes it, weekly review scheduled, everything synced to exams. Chat until you can pick the right procedure for a scenario and explain a p-value in plain English, because procedure selection and interpretation are where this course's exams are decided.
FAQ
Is STAT 2120 at UVA hard?
It's manageable but unforgiving of gaps: every unit builds on the last, and students who skim probability rarely recover when inference arrives. The exams reward procedure selection and interpretation over computation, which surprises formula-focused studiers.
Do I need calculus for STAT 2120?
No — algebra suffices. The difficulty is conceptual: understanding what sampling distributions, intervals, and tests mean, and matching procedures to scenarios. Students wanting a calculus-based treatment take the math-stat track instead.
How do I study for STAT 2120 exams?
Drill scenario-to-procedure matching — given a study description, name the right test or interval and why — and write a one-sentence plain-English interpretation for every practiced answer. Review cumulatively each week, since the regression finale assumes the entire course at once.

CS 1110 — Introduction to Programming
CS 1110 is UVA's Python-based introduction to programming, assuming no prior experience — the entry point for prospective CS majors, minors, and a wide range of other students. It covers variables, control flow, functions, lists and dictionaries, file handling, and basic objects, with weekly labs and programming assignments.
CS 2100 — Data Structures and Algorithms 1
CS 2100 is the first course of UVA's renumbered CS core — data structures and algorithms in Java, covering lists, stacks, queues, trees, hash tables, and runtime analysis, with required labs alongside lecture. It replaced the old CS 2110/2150 path and is the gateway the rest of the major builds on.
CS 2120 — Discrete Mathematics and Theory 1
CS 2120 is the discrete math course of UVA's CS core — logic, proofs, sets, functions, induction, and basic graph and number theory — the mathematical foundation for algorithms and theory courses later in the major. It's most students' first proof-based course.
CS 2130 — Computer Systems and Organization 1
CS 2130 takes UVA CS students below the languages they know — binary representation, gates and circuits, assembly, and C programming with pointers and memory — building a working model of how computers actually execute code. Labs run alongside lecture, and it leads into CSO2.
