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.
Statistics AI: Hypothesis tests that
pick the right test.
AskSia walks t-tests, ANOVAs, chi-squared, and regression diagnostics with assumptions checked at every step. Built for Intro Stats, Math Stat, AP Stats, Stata/R/Python coursework, and the regression class everyone calls 'the methods class'. Web, mobile, LMS extension, desktop.

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.
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.
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.
Lecture, RStudio, dataset, exam review.
Phone in section for a quick test-selection check. Laptop in RStudio. Extension pulling Stat 110 from your LMS. Desktop agent over your Stata window at midnight. One stats library, four surfaces.
The stats workbench in your browser
Drag your dataset, the textbook PDF, your problem sets, and your professor's slides in. AskSia runs the test selection logic, walks the assumptions, and answers across all 100 files with page citations.
Snap-and-pick-the-right-test
iOS and Android. Photograph the problem, the dataset summary, or the test output. AskSia returns the right test, the correctly-stated hypotheses, and the assumption check in seconds.
Pulls your stats term in 30 seconds
The Chrome extension adds a Sync button on Canvas, Blackboard, Brightspace, Moodle, and Everytime. Your stats syllabus, datasets, problem sets, and TA solutions pull into one searchable library.
Cmd+Space over RStudio or Stata
Native macOS and Windows. AskSia summons over RStudio, Stata, SPSS, Jupyter, or your textbook PDF. Reads your selected code or output and explains what the test actually told you.
12 study tools built
for college statistics.
Stop juggling StatTrek for formulas, ChatGPT for R code (where it hallucinates packages), Khan Academy for the basics, and your TA's office hours for everything else. AskSia is one workspace grounded in your real stats coursework.
Stats lecture transcription
Record your Intro Stats, Stat 110, or methods class lecture. 40+ languages, sub-100ms latency, statistical terminology and formula notation preserved.
OpenStats multi-PDF Q&A
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.
OpenHypothesis 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.
OpenYouTube 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.
OpenStats 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.
OpenSia Note for stats chapters
Turns a 150-page chapter on regression into one note: model assumption, diagnostic, interpretation rule, worked example, exam-style problem.
OpenR/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.
OpenStats flashcards · FSRS
Auto-built decks: test selection logic, distributions, regression assumptions, R/Stata commands. FSRS spacing tuned to your exam.
OpenStats 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.
OpenAI 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.
OpenTrained on real coursework at
the world's top universities.
Browse by university, subject, or course. Every entry maps to curated study patterns for that program.
