Real outcomes

It's not the p-value. It's grades.

Stats students lose points for picking the wrong test, mis-stating the null, or forgetting to check normality before running parametric methods. The students below stopped losing those points the week they started using AskSia.

2.9->3.6+0.7

AskSia walked me through hypothesis testing on my STAT110 problem set with the null and alternative spelled out for every problem. I stopped second guessing one tailed versus two tailed.

3.2->3.8+0.6

For regression I dropped my dataset into AskSia and got a Sia Note explaining every diagnostic plot. Residuals versus fitted finally meant something instead of just being a picture.

Lukas · Stats

3.0->3.7+0.7

The Mock Exam mode generated AP Stats free response with the rubric applied. Auto graded explanations told me exactly which point I lost for not stating conditions.

Drop Casella & Berger, Wasserman, your lecture slides, problem sets, and 80 papers. Ask 'why does this test require independence' and AskSia answers with page-cited proof.

Open

Hypothesis test selector

Reads your dataset description or problem. Returns the right test (t/ANOVA/chi-squared/nonparametric), correctly-stated null and alternative, and the assumption checks you need to run first.

Open

YouTube to stats notes

Paste any StatQuest, 3Blue1Brown linear algebra, or Khan Academy stats URL. AskSia transcribes, chapterizes, and pulls the worked examples into a clean note.

Open

Stats Mock Exam mode

Adaptive practice tuned to your real Intro Stats, AP Stats, or methods class patterns. Catches the test-selection and assumption errors you keep making.

Sia Note for stats chapters

Turns a 150-page chapter on regression into one note: model assumption, diagnostic, interpretation rule, worked example, exam-style problem.

Open

R/Stata/Python code reviewer

Reads your stats code line by line. Flags wrong test choice, missing assumption checks, and the lurking 'NA' that's silently dropping your sample. Suggests fixes.

Open

Stats flashcards · FSRS

Auto-built decks: test selection logic, distributions, regression assumptions, R/Stata commands. FSRS spacing tuned to your exam.

Open

Stats concept map

The whole curriculum as a navigable tree from descriptive stats through Bayesian inference. Each node linked to its textbook page and lecture timestamp.

Open

AI tutor for stats

Voice-first or text. Walk through the central limit theorem three different ways, drill confidence interval interpretation, or explain why Bayes isn't actually a black box.

FAQ

Frequently asked
questions.

Can AskSia pick the right hypothesis test for my problem?
Yes. Given your data description (sample size, paired/independent, normality, variance), AskSia returns the right test (one-sample t, paired t, Welch's t, ANOVA, Kruskal-Wallis, chi-squared, etc.), correctly states the null and alternative, and runs the assumption checks first. Strong on Intro Stats, Stat 110, and methods-track courses.
Does AskSia handle regression diagnostics?
Yes. AskSia walks residuals vs fitted, QQ plots, scale-location, Cook's distance, and VIF in the conventions your textbook uses (Gelman & Hill, Wooldridge, Faraway). Strong on Stat 139 (Harvard), 154 (Berkeley), and undergraduate econometrics courses.
Will AskSia help with AP Statistics prep?
Yes. AskSia runs the College Board FRQ patterns, drills inference and experimental design content, and times you against the real AP Stats sections. Tracks which topics (sampling distributions, type I/II errors, regression inference) are still costing you points.
Can AskSia review my R, Stata, or Python stats code?
Yes. AskSia reads your tidyverse, base R, Stata, SPSS, JASP, or Python stats code. Flags wrong test choice, missing assumption checks, mis-clustered standard errors, and silently-dropped NAs. Suggests fixes without rewriting your code for you.
Is AskSia free for statistics students?
Yes, AskSia is free for statistics students to start, no credit card required. Free includes daily generation across all tools, unlimited library access, and the browser extension. AskSia Pro and Super unlock unlimited generation, full Mock Exam mode, free-response auto-grading at scale, priority models, and unlimited transcription minutes.
Which platforms does AskSia run on?
Four surfaces, all syncing in real time: (1) Web app at asksia.ai, (2) iOS and Android mobile apps, (3) Browser extension for Chrome, Edge, Brave, and other Chromium browsers, which adds Sync to AskSia on Canvas, Blackboard, Brightspace, Moodle, and Everytime, (4) Native desktop agent for macOS and Windows.
Does AskSia handle Bayesian stats?
Yes. AskSia walks prior/likelihood/posterior derivations, runs conjugate updates, and explains MCMC convergence diagnostics. Strong on Gelman et al BDA3 and Kruschke patterns. Handles Stan, PyMC, and brms code review.
Can AskSia help with stats for psychology or biology coursework?
Yes. AskSia handles the discipline-specific frameworks: APA reporting for psych (Cohen's d, eta-squared, partial eta-squared), bioinformatics adjustments for multiple comparisons (Bonferroni, FDR, Benjamini-Hochberg), and the experimental-design vocabulary your field actually uses. Strong on Field's Discovering Statistics and Whitlock & Schluter.
Is AskSia OK for SOA exams (P, FM) and CFA Level 1 quant?
Yes. AskSia drills the SOA Exam P probability distributions and the FM time value of money problems in the actual exam format. Same for the CFA Level 1 quant section. Mock Exam mode times you against the real conditions and tracks topic-cluster weakness.
