Cornell AEM 2100: Introductory Statistics
AEM 2100 is the Dyson School's introductory statistics course — descriptive statistics, probability and distributions, sampling, confidence intervals, hypothesis testing, and regression — taught with applications to business and economics and the statistical software students use in the field. It satisfies the quantitative-methods requirement for AEM majors.

Build my AEM 2100 study planWhat makes it hard
The course is cumulative and the failure pattern is predictable: students cruise through descriptive stats, treat probability casually, then drown when inference arrives and assumes both. Exams emphasize interpretation — choosing the right procedure and explaining results in a business context — which pure formula memorizers consistently miss.
What you'll cover
- • Descriptive statistics and graphs
- • Probability and distributions
- • Sampling distributions
- • Confidence intervals
- • Hypothesis testing
- • Correlation and regression
The AEM 2100 study guide
How to study for Cornell AEM 2100, step by step.
- 1
Take probability seriously while it's easy to
AEM 2100's failure pattern is cruising through descriptive stats, treating probability casually, then drowning at inference. The probability weeks are the foundation — give them full effort.
- 2
Practice scenario-to-procedure matching
Given a problem, decide which test or interval applies and why — before computing anything. Exams emphasize procedure selection and context, which is exactly what formula memorizers miss.
- 3
Write a plain-English sentence for every result
Each practiced interval or test ends with one sentence interpreting it in business context. That format is what exam questions reward, and the habit makes the concepts stick.
- 4
Use the software to understand, not just compute
The course uses statistical software, but the points are in interpreting the output, not generating it. Read each result and explain what it means before moving on.
- 5
Review cumulatively every week
Inference assumes probability and sampling distributions fluently. Fold a few earlier-unit questions into each week's study so nothing has gone cold by exam time.

How Fennie helps with AEM 2100
Fennie's Daily Plans hold the cumulative line in AEM 2100 — probability locked down before inference, review synced to exams. Chat until you can pick the right procedure for a business scenario and explain a result in plain English, because interpretation in context is where these exams are won.
FAQ
Is AEM 2100 at Cornell hard?
It's manageable but unforgiving of gaps: every unit builds on the last, and students who fall behind before hypothesis testing rarely catch up. The exams reward interpretation and procedure selection over raw calculation.
Do I need calculus for AEM 2100?
No — algebra is sufficient. The challenge is conceptual: understanding what sampling distributions, intervals, and tests mean, and matching procedures to business scenarios, rather than any difficult computation.
How do I study for AEM 2100 exams?
Practice scenario-to-procedure matching: given a problem, decide which test or interval applies and why, before computing. Write a one-sentence plain-English interpretation for every answer — that's the format these exams reward.

CS 1110 — Introduction to Computing: A Design and Development Perspective
CS 1110 is Cornell's Python-based first programming course — variables and types, functions, conditionals and loops, objects and classes, recursion, and testing — taken by intended CS majors and a large non-major population alike. It leads into CS 2110 for those continuing in the major.
CS 2110 — Object-Oriented Programming and Data Structures
CS 2110 is Cornell's second programming course, taught in Java (cross-listed as ENGRD 2110) — object-oriented design, data structures (lists, trees, hash tables, graphs), recursion, and an introduction to algorithmic analysis. It's the gateway most CS and engineering students name as the major's first real workload jump.
CS 2800 — Discrete Structures
CS 2800 is Cornell's discrete mathematics course for CS majors — logic and proof, induction, sets, functions and relations, combinatorics, graph theory, basic probability, and finite-state machines. It's the bridge from coding to the mathematical reasoning the upper-level theory courses assume.
CS 3110 — Data Structures and Functional Programming
CS 3110 is Cornell's famous functional-programming and data-structures course, taught in OCaml — immutability, recursion, higher-order functions, modules and functors, formal specification and verification, and reasoning about correctness and complexity. It's a required CS core course and a notorious pace step-up after CS 2110.
