Math Says Yes: Statistics

Fresh facts every week: the birthday paradox, why one poll of 1,000 people works, when an average hides everything. Swipe, guess, then see the data. Free to read.

Most statistics sound wrong at first.

In a room of 23 people, the odds of a shared birthday are already even. On a game show with three doors, switching after the host opens one doubles your chance of winning. A poll of 1,000 strangers can read a whole country. Math Says Yes is a feed of facts like these, each one explained until the surprise turns into something obvious.

Open the app and start scrolling. Every fact is short and sourced, built around a single idea from probability or data. Most come with a quick question that catches your gut before it shows the answer, plus a small chart or a slider you can play with to watch the number move.

What's inside:

• A scrolling feed of counterintuitive statistics, from the birthday paradox to why tiny samples lie
• Quick-check questions tuned to the exact intuition people get wrong
• A daily challenge of five questions, so you can find out whether you beat your own guessing
• Search and topics for digging into probability, sampling, averages, or plain randomness
• Saved facts and a "learned" marker to track what has actually stuck
• A glossary that explains the jargon in one paragraph instead of one textbook

It costs nothing to read and needs no signup to start. Sign in only if you want to save facts or keep your progress.

Made for the people who liked statistics in theory but never quite trusted it, and for anyone who enjoys being pleasantly wrong about numbers.
