UIUC STAT 100: Statistics
STAT 100 is UIUC's introductory statistics course for non-majors — descriptive statistics, probability basics, correlation and regression, and inference — and one of the largest courses on campus. It's a popular quantitative-reasoning requirement filler known for well-produced lectures and a heavily structured format.

Build my STAT 100 study planWhat makes it hard
It's deliberately accessible, which lulls students into autopilot — then the inference material (confidence intervals, hypothesis testing) requires actual conceptual care, and exam questions on interpretation expose anyone who only memorized procedures. The volume of small graded components also punishes disorganization more than difficulty does.
What you'll cover
- • Descriptive statistics and distributions
- • Correlation and regression
- • Probability basics
- • Sampling and the normal curve
- • Confidence intervals
- • Hypothesis testing
The STAT 100 study guide
How to study for UIUC STAT 100, step by step.
- 1
Track every small graded component
STAT 100's grade risk is organizational — the volume of small assignments punishes disorganization more than difficulty does. Put every deadline in one place in week one and never miss a free point.
- 2
Stay engaged when it feels easy
The accessible early material lulls students into autopilot right before inference arrives. Keep doing the practice questions properly so confidence intervals and hypothesis testing land on an active brain.
- 3
Practice plain-words interpretation
Exam questions expose anyone who memorized procedures without meaning. For every interval and test, write one sentence stating exactly what it concludes — and what it doesn't.
- 4
Use the practice questions in volume before exams
The course's structured format means practice materials closely mirror the exams. Work them as real rehearsal, focusing on the interpretation questions where easy-course grades leak.

How Fennie helps with STAT 100
Fennie's Daily Plans keep STAT 100's many small deadlines and steady content drip organized alongside your heavier courses. Use chat to lock in what confidence intervals and p-values actually mean — the interpretation questions are where easy-course grades leak — and run generated quizzes before each exam.
FAQ
Is STAT 100 easy at UIUC?
It's among the most approachable quantitative courses on campus, with strong course materials and a predictable structure. The grade risks are organizational — missed small assignments — and conceptual sloppiness on inference interpretation questions, both fully avoidable.
Does STAT 100 count for the quantitative reasoning requirement?
Yes, it satisfies quantitative reasoning credit for many majors, which is a big part of its enrollment. Majors needing calculus-based statistics take other courses, so check your degree audit before assuming it counts.
How do I get an A in STAT 100?
Never miss the small graded components, and study inference conceptually — be able to explain in plain words what an interval or test concludes. The exams reward clean understanding over memorized steps.

STAT 107 — Data Science Discovery
STAT 107 is UIUC's introductory data science course, jointly designed by Statistics and Computer Science — Python in notebooks, data manipulation, visualization, simulation-based inference, and machine learning basics, all taught through real datasets. It assumes no programming background and has become one of the most popular ways into data skills on campus.
STAT 400 — Statistics and Probability I
STAT 400 is UIUC's calculus-based probability and statistics course — probability, random variables, common distributions, expectation, the central limit theorem, then estimation, confidence intervals, and hypothesis testing. It's the workhorse statistics requirement for CS + Statistics, actuarial science, and many engineering and quantitative majors.
