UIUC 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.

Build my STAT 107 study planWhat makes it hard
Beginners juggle two new skills at once — Python and statistical thinking — and the course's project-driven format means deadlines reward steady work over brilliance. The simulation-based inference ideas read as easy until exam questions demand interpreting results precisely, where hand-waving stops working.
What you'll cover
- • Python and Jupyter notebooks
- • Data manipulation with DataFrames
- • Data visualization
- • Simulation and randomness
- • Hypothesis testing and confidence intervals
- • Introduction to machine learning
The STAT 107 study guide
How to study for UIUC STAT 107, step by step.
- 1
Code along, never just watch
STAT 107 teaches Python through doing, and passively following notebooks builds an illusion of competence. Retype, modify, and break every example — the friction is where the learning is.
- 2
Keep the project pipeline moving
The project-driven format rewards steady weekly progress over deadline heroics, especially for beginners debugging their first Python. Start each project's data-loading step the day it's assigned.
- 3
Practice interpretation in plain sentences
Exam questions ask what a simulation result or confidence interval actually concludes — and what it doesn't. Write one plain-English sentence for every inference you compute, every time.
- 4
Build a personal snippet library
Filtering DataFrames, grouping, plotting — the same patterns recur all semester. Keeping your own annotated snippets turns every later assignment into assembly rather than search.

How Fennie helps with STAT 107
Fennie's Daily Plans grow STAT 107's two skills in parallel — steady Python reps and the statistical thinking exams actually grade. Chat through what a p-value or interval really concludes when the notebook makes it look automatic, and drill generated interpretation quizzes before each exam.
FAQ
Is STAT 107 hard at UIUC?
It's deliberately beginner-friendly, with no programming assumed — the challenge is juggling new Python skills and new statistical thinking at once. Students who code along actively and keep project work steady find it one of the best-supported intro courses on campus.
Do I need coding experience for STAT 107?
No — Python is taught from zero inside the course. Complete beginners should budget extra time in the first weeks for environment friction and syntax errors; that investment pays back across the whole semester.
What's the difference between STAT 107 and STAT 100?
STAT 100 is a concepts-first statistics survey without programming; STAT 107 teaches data science hands-on in Python with projects. Pick 107 if you want practical data skills and 100 if you want the lighter conceptual route to the requirement.

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.
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.
