Real outcomes
It's not the p-value.
It's the grade.
Stats students lose points for one wrong test (t-test where Mann-Whitney was right), a regression diagnostic that missed heteroskedasticity, or a Bayesian prior chosen without justification. AskSia catches what your TA catches.
3.2->3.8+0.6
For regression for DS I dropped my dataset into AskSia. Got a Sia Note explaining every diagnostic plot. Residuals versus fitted finally meant something practical.
3.0->3.7+0.7
The Mock Exam mode generated stats DS problems with auto graded numerical answers. Pointed out exactly which test I should have used for the proportion problem.

Everything in one place
12 study tools built for stats-for-DS.
Stop juggling scipy for tests, statsmodels for regression, ChatGPT for inference (that confuses Type I with Type II error), and your TA's office hours. AskSia is one workspace.
Stats lecture transcription
Record your stats-for-DS lecture. 40+ languages, sub-100ms latency, statistical notation preserved.
OpenStats multi-source Q&A
Drop ISL, your textbooks, datasets, and 80 papers. Ask 'why use bootstrap CI instead of normal approximation' and AskSia answers with cited proof.
OpenHypothesis testing walker
Walks t-test, chi-squared, ANOVA, non-parametric tests with the right choice for the data. Catches the assumption violations that pick wrong test.
OpenYouTube to stats notes
Paste any StatQuest, 3Blue1Brown, or Khan Academy stats URL. AskSia transcribes, chapterizes, pulls the worked examples into a clean note.
OpenStats Mock Exam mode
