Every unit, fully covered
Targeted review of all nine AP Statistics units, weighted by exam importance.
Exploring One-Variable Data
Distributions, center, spread, normal model, and z-scores. Learn to describe and compare distributions using shape, center, spread, and outliers.
Exploring Two-Variable Data
Scatterplots, correlation, least-squares regression, and residual analysis. Interpret slope, intercept, and r-squared in context.
Collecting Data
Sampling methods, sources of bias, experiments vs. observational studies, random assignment, and the scope of inference.
Probability & Random Variables
Probability rules, binomial and geometric distributions, expected value, standard deviation, and combining random variables.
Sampling Distributions
Central limit theorem, sampling variability, conditions for inference, and the behavior of sample statistics across repeated samples.
Inference (Units 6–9)
Confidence intervals, hypothesis tests for proportions and means, chi-square tests, inference for regression slopes, Type I and Type II errors, and power. This is the largest section of the exam — we dedicate the most time here.
Full-Year Academic Schedule (Sept 2026 – May 2027)
Designed to keep you ahead of your classroom lectures, unit tests, midterms, and the May 2027 AP Exam.
Units 1–3: Data & Linear Regression
Histograms, z-scores, normal distributions, least-squares regression lines, residuals, and experimental design.
Units 4 & 5: Probability & Sampling
Probability rules, conditional probability, binomial/geometric models, Central Limit Theorem & Fall midterms.
Units 6 & 7: Proportions & Means Inference
1-sample and 2-sample z/t confidence intervals, hypothesis significance tests, p-values, Type I/II errors & power.
Units 8 & 9: Chi-Square & Slope Inference
Goodness-of-fit, homogeneity, independence tests, linear regression t-tests, and computer output interpretation.
Investigative Task & Exam Blitz
Question 6 Investigative Task mastery, contextual rubric writing workshops, full diagnostic mocks & final test prep.
Live Sessions & 1-on-1 Add-On

How to score a 5 on AP Statistics
Strategies from 8+ years of tutoring AP Stats students.
Master the 4-Step Inference Framework
State, Plan, Do, Conclude. Every free-response question on inference follows this structure. Learn it, practice it, and never skip a step. Graders are looking for all four parts.
Check Conditions Every Time
Random, Normal, Independent — the exam always asks about conditions. Whether it's a confidence interval or hypothesis test, you must verify conditions to earn full credit.
Practice the Investigative Task
Unique to AP Statistics, the investigative task is a multi-part question that requires data analysis, interpretation, and clear written communication. It can make or break your FRQ score.
Know When to Use Which Test
Z-test, t-test, chi-square, regression slope — create a decision flowchart. Know the conditions, formula, and interpretation for each test type. This clarity saves time on exam day.
Write in Complete Sentences
AP Statistics rewards clear communication. Practice writing conclusions in context — not just "reject H0" but "there is convincing evidence that the mean score is greater than 70." Context matters.
Know what you're walking into
The AP Statistics exam has a unique structure — understanding it gives you a strategic edge.

AP Statistics questions
You get complete continuous support: weekly live Zoom office hours to solve difficult problem sets, hypothesis testing templates, calculator command guides (TI-84/TI-Nspire), and 24/7 personal Q&A directly with Sid so you never get stuck on inference conditions or interpretations.
The investigative task is Question 6 on the AP Statistics free-response section — an extended multi-part question testing innovative statistical thinking. Inside the community, we break down past Question 6 rubrics, teaching you exact phrasing strategies to secure full credit.
1-on-1 private tutoring is available at $50/hour. You can book custom sessions anytime for individualized problem set walkthroughs, calculator coaching, or upcoming chapter exam prep.
A TI-84 Plus (or TI-84 Plus CE) is the most popular and recommended calculator. The TI-Nspire (non-CAS) is also widely used. We provide specific cheat sheets for key calculator functions like 1-PropZTest, 2-SampTTest, Chi-Square GOF, and LinRegTTest.
