Need AP Statistics tutoring? At PY Education, this subject is taught by founder and principal tutor Tinnie. She holds an MSc in Finance and Economics from the London School of Economics (Distinction), first-class honours degrees in Accounting and Finance and in Data Science and Business Analytics from the University of London, and a BBA in Professional Accountancy from CUHK. She teaches mathematics for GCSE / IGCSE, GCE A-Level / IAL (including Further Mathematics), IBDP and AP.
Taught to College Board’s course framework and its published scoring guidelines, covering exploring data, sampling and experimental design, probability and distributions, statistical inference and regression analysis, with past free-response questions used for practice. One-to-one private tutoring, 1 hour a lesson, in Kwun Tong or online. Students whose school does not offer AP can enrol as self-study candidates, and the first lesson can be a free trial.
This page describes College Board’s Course and Exam Description, Effective Fall 2026 — that is, the May 2027 examination onwards. This version gathers the previous nine units into five:
The Course and Exam Description (Effective Fall 2026) sets out the approximate weighting of the multiple-choice section: Unit 1, 20–30%; Units 2 and 3, 15–25% each; Units 4 and 5, 10–20% each. The free-response section is not weighted unit by unit.
The May 2026 examination and the ones before it use the older nine-unit course, and the reorganisation is not only a renumbering: the geometric distribution, the chi-square goodness-of-fit test and inference for slopes are all outside the new course framework. A student working from an older textbook or older past papers will have several exercises that the new version no longer asks for, and we go through item by item which of them can be skipped.
The first four lessons usually start with Units 1 and 2: describing one-variable distributions, sampling methods, experimental design, and random variables and their parameters. Inference questions ask for the conditions of a procedure to be verified first, and those conditions come straight out of these two units, so we would rather spend a few more lessons here than move on to inference quickly.
Unit 1 begins with an investigative question: the student first settles what type each variable is, then chooses a suitable graph and suitable statistics. Most of what is examined here is description rather than calculation — a question that says “describe this distribution” carries separate marks for shape, centre, spread and outliers, and all four have to be written down.
Key topics: describing distributions, dotplots and boxplots, the five-number summary, standard deviation, z-scores, outliers, comparing distributions.
This part tests judgement: whether a study is an experiment or an observational study, how the randomisation was done, whether anything is confounded. We work through real study scenarios so that a student can give the reason behind every design choice, rather than reciting a classification table.
Key topics: simple random sampling, stratified sampling, cluster sampling, bias in sampling, experimental design, randomisation, control, matched pairs, confounding.
Unit 2 opens with two-way tables for two categorical variables, moves through probability and conditional probability, and runs on to random variables, distributions and the central limit theorem.
Key topics: conditional probability, mutually exclusive events, independent events and unions of events, random variables and their parameters, the binomial distribution, the normal distribution, sampling distributions and the central limit theorem.
Two things are worth settling early: the new course framework has no geometric distribution, where the old one did; and AP Statistics has no Poisson distribution at all, which is where a student also taking DSE Mathematics Extended Part Module 1 meets a difference.
Units 3 and 4 are the body of the inference work, the first for proportions and the second for means. Every inference is written the same way: state the hypotheses, verify the conditions, calculate, then put the conclusion back into the context of the question. We practise the four steps separately, and put them together into a whole question once they are settled.
Unit 5 deals with the relationship between two quantitative variables. Questions ask for one of two things more often than anything else: interpreting the slope and the intercept back in the context, or reading a residual plot to judge whether a linear model is appropriate — and for the second, “the residual plot shows no clear pattern” still leaves what that means to be said.
Key topics: scatterplots, correlation, linear regression models, residuals and residual plots, least-squares regression, the coefficient of determination.
This is the examination format from May 2027 onwards. The paper runs 3 hours in two sections weighted 50% each: Section I is 42 multiple-choice questions in 90 minutes, four options per question; Section II is 4 free-response questions in 90 minutes, 10 points each, the four carrying equal weight at 12.5% of the paper apiece.
The four free-response questions have fixed roles: Question 1 concentrates on statistical practices 1 and 2, Question 2 on practices 3 and 4, Question 3 is always an inference question — a hypothesis test or a confidence interval — and Question 4 runs across several content areas while assessing practices 2, 3 and 4. Since Question 3 is always inference, we put the four-step inference practice early.
From May 2027 the whole paper is answered digitally inside the Bluebook application, with no paper free-response booklet, and the Investigative Task has been discontinued. The May 2026 paper has 6 free-response questions, the last of which is the Investigative Task — so on a paper from that year or earlier, the number of questions and the question types both read differently.
A graphing calculator with statistical capabilities is expected in both sections, and the formula sheet and statistical tables are supplied by College Board in the paper.
The AP Statistics scoring guidelines ask for the conclusion in the terms of the question — “there is sufficient evidence that the mean weight at this plant is below the labelled value”, not simply “reject the null hypothesis”. That sentence has a settled shape, and it is used on every inference question, so we practise it question by question.
Free-response questions are marked on an analytic scale, point by point, rather than on the final answer alone: choosing the procedure, verifying the conditions, calculating and interpreting each carry their own points. We mark question by question against College Board’s published scoring guidelines, until the way an answer is written settles.
A graphing calculator with statistical capabilities is expected in both sections of the examination. Which steps can be handed to the calculator and which have to be written out on the paper are two separate questions — the t statistic and the p-value can come off the machine, but which test was chosen, why that one, and whether the conditions hold still have to be written in the student’s own words. We teach the calculator work and the written account together.
The same tutor teaches IB, A-Level and DSE mathematics, so this comparison comes from teaching both sides. The statistics in IB Applications and Interpretation (AI) overlaps AP Statistics plainly: regression, the chi-squared test, the t-test and the normal distribution appear in both. The difference is that AP Statistics is statistics throughout, with sampling and experimental design forming a large part of its own, while on the IB side statistics is one topic within the mathematics course; IB also has a school-based Exploration that counts towards the grade, whereas every AP Statistics point comes from the single examination in May.
As for DSE Mathematics Extended Part Module 1 (Calculus and Statistics), its distributions are the binomial, Poisson and normal distributions, with the weight on calculation; AP Statistics has no Poisson distribution, and its weight falls on study design and on how a conclusion is expressed. If a student is taking both, we work out together in the free trial lesson how the lessons should be divided.
Students whose school does not offer AP Statistics can enrol. A self-study candidate finds a test centre that accepts external candidates and handles the registration, and we go through that part in the trial lesson. The schedule is planned from the beginning and worked backwards from the May examination date: Units 1 and 2 in the early part, inference and regression later, with lessons kept back for whole papers.
The trial lesson starts with where the student is now and where the weak points are, confirms which exam year is being taken and which version of the course framework the school is using, and then discusses which unit to start from. There is no obligation to enrol on the day.

Yes — the new version starts with the May 2027 examination. It has five units, 42 multiple-choice questions plus 4 free-response questions, 90 minutes for each section, answered digitally inside Bluebook, and the Investigative Task is gone. May 2026 and earlier follow the nine-unit course with 6 free-response questions, the last of them the Investigative Task. That is why an older paper does not match on the question count, the question types or the unit numbering. Tell us which exam year you are taking when you enrol and we will plan to that version.
Yes. The algebra it asks for is modest; the demand is in judgement and in how an answer is expressed. Students who are strong at mathematics should look closely at the conclusion — they are used to writing the mathematical result on its own, without putting the conclusion back into the context of the question.
Yes. A self-study candidate finds a test centre that accepts external candidates and handles the registration, and we go through that part in the trial lesson. The schedule is planned from the beginning and worked backwards from the May examination date: Units 1 and 2 first, inference and regression later, with lessons kept back at the end for whole papers.
AP reports a score from 1 to 5, subject by subject, and there is no diploma for AP Statistics on its own. Which score earns university credit or exemption is each university’s own policy and it changes, so read the admissions page of the university you are aiming for. We do not quote a threshold score.
Because the points are awarded one at a time. In the new version each free-response question is worth 10 points, marked on an analytic scale: choosing the procedure, verifying the conditions, calculating and interpreting each carry their own points, and all four have to be written down. We mark question by question against College Board’s published scoring guidelines, so you can see which point went unwritten.
A good deal overlaps — regression, the chi-squared test, the t-test and the normal distribution appear in both. The difference is that AP Statistics is statistics throughout, with sampling and experimental design forming a large part of its own, while on the IB side statistics is one topic within the mathematics course; IB also has an Exploration that counts towards the grade, whereas every AP point comes from the single examination in May. Both are taught here, and we can talk it through in the trial lesson.
Yes, subject to the timetable. The two are approached quite differently, so if you take both we keep them in separate lessons rather than combining them.
Online lessons are available at the same rate as face-to-face lessons in Kwun Tong, and students overseas can attend as long as the time difference works. Lessons are held over video call — Zoom or another application, agreed when you enrol. AP is one-to-one only, with no group option. We do not teach at students’ homes: Kwun Tong or online are the two options.
Yes. The first lesson can be a free trial — tick the box on the enrolment form. The trial starts with where the student is now and where the weak points are, confirms which exam year is being taken and which version of the course framework the school is using, and then discusses which unit to start from. There is no obligation to enrol on the day. Lessons are in Kwun Tong or online, 60 minutes each.
There is no single answer, and we do not promise a particular grade. We look at three things: whether the same type of question comes out right the second time; marks dropped on questions the student can do, where a condition went unverified or the context was left out of the conclusion; and whether a section gets finished in its 90 minutes. Each of the three decides what the next lesson does — the first sends us back to the concept, the second to how an answer is written, the third to timing.
Yes, and each course has its own page and its own fees. Note that the lesson lengths differ: IGCSE, IAL, IBDP and AP lessons are 60 minutes and charged by the hour, while DSE and primary lessons are 75 minutes and billed every four lessons. See the individual course pages, or we can go through it all in the trial lesson.
