UCLA STATS 10: Introduction to Statistical Reasoning

STATS 10 is UCLA's introductory statistics course for non-majors, covering data collection, visualization, probability basics, and inference, with computational work in R. It satisfies statistics requirements across many majors and draws students from every corner of campus.

Fennie is independent and not affiliated with UCLA. This is an unofficial study guide.

What makes it hard

It's one of the gentler quantitative courses at UCLA, but the quarter pace still bites: inference concepts arrive quickly, and students who treat early weeks as easy fall behind for the conceptual back half. R is new to most students, and exam questions on interpreting p-values and confidence intervals punish vague understanding.

What you'll cover

  • • Data collection and study design
  • • Descriptive statistics and visualization
  • • Probability basics
  • • Sampling distributions
  • • Confidence intervals
  • • Hypothesis testing
  • • Introductory R

The STATS 10 study guide

How to study for UCLA STATS 10, step by step.

  1. 1

    Don't autopilot the easy early weeks

    STATS 10's gentle start lulls students into coasting — then the inference unit arrives on quarter-system pacing. Stay genuinely engaged through descriptive statistics so the back half builds on something solid.

  2. 2

    Get comfortable in R right away

    R is new to most STATS 10 students, and lab friction is avoidable. Run the lab code yourself early, change things to see what breaks, and the tool fades into the background by midterm time.

  3. 3

    Learn what p-values and intervals actually claim

    Exam questions on interpretation punish vague understanding. Practice writing one-sentence plain-English statements of what a confidence interval or test result does and doesn't conclude.

  4. 4

    Drill interpretation-style questions before exams

    The exam's favorite format is handing you output or a scenario and asking what it means. Practice that specific question style, not just the computations behind it.

How Fennie helps with STATS 10

Upload the STATS 10 schedule and Fennie's Daily Plans spread the course evenly across the quarter so the inference unit — where grades are decided — gets unhurried attention. Use chat to nail what p-values and confidence intervals actually claim, and run generated quizzes on interpretation questions, the exam's favorite format.

FAQ

Is STATS 10 hard at UCLA?

It's among the more approachable quantitative GEs, but it isn't free — inference interpretation questions trip up students who only memorized procedures. Keep up weekly and the course is very manageable on a quarter timeline.

Does STATS 10 use R?

Yes, labs use R (typically through RStudio) for data analysis, assuming no prior programming. The R component is guided and graded gently; exam performance rests on statistical reasoning rather than coding skill.

Does STATS 10 satisfy my major's statistics requirement?

It satisfies the statistics requirement for many non-STEM and life-science-adjacent majors, but some majors require STATS 13 or a calculus-based course instead. Check your specific major requirements before enrolling.

Pass STATS 10 with a plan, not a cram

More UCLA courses

CS 31 — Introduction to Computer Science I

CS 31 is UCLA's intro programming course, taught in C++, covering control flow, functions, arrays, pointers, and basic program design. It's the first required course for CS majors and a common choice for engineering and math students adding programming skills.

CS 32 — Introduction to Computer Science II

CS 32 is UCLA's data structures course in C++, covering recursion, linked lists, stacks, queues, trees, hash tables, and algorithm analysis. Its multi-thousand-line projects — including the famous game-engine project — are a step change in scale from CS 31.

MATH 31A — Differential and Integral Calculus

MATH 31A is UCLA's first calculus course — limits, derivatives, optimization, and the basics of integration — required across engineering, physical science, economics, and life-science-adjacent tracks. Most STEM freshmen take it (or skip it via AP credit) in fall quarter.

MATH 31B — Integration and Infinite Series

MATH 31B covers integration techniques, applications, improper integrals, and infinite sequences and series including Taylor series. It's the second course in UCLA's main calculus sequence and a prerequisite for the multivariable courses that follow.
