A ten-minute lesson in reading data instead of gut feel
Progress Tab’s quiz asks eight questions about global health, poverty and education. Students guess first, then see the sourced number — and the gap between the two is the lesson. No install, no account, no prep beyond opening a link.
How to run it in 10 minutes
Open the quiz
Open progresstab.app/quiz on the projector, or share the link so each student opens it on their own device — phone, laptop, or the classroom computer all work.
Guess as a class
For each question, students pick one of three options — by a show of hands, or written down first if you want individual answers on paper — before the real number appears.
Reveal, then talk for a minute
Tap to reveal the sourced number and spend a minute on the gap: why did the class guess darker (or lighter) than the data? What made that problem feel bigger than the numbers say?
Close with the score
After all eight questions, the quiz shows how the class’s guesses compared to the real numbers. That gap — between what felt true and what’s measured — is the actual lesson, more than any single fact.
Why it’s safe to open in class
It’s a web page, not an extension, so it runs on a locked-down school computer the same as anywhere else.
Nothing to sign up for, and this site sets no cookies — nothing to explain to a parent or an IT department.
Each answer links to its primary source — the WHO, the World Bank, Our World in Data — so a curious student can verify it.
What research says
The misses ran in one direction — toward a darker, poorer, sicker picture of the world than the data shows, often worse than picking answers at random.
The method here — guess first, then reveal — comes from Hans Rosling and the Gapminder Foundation, who spent years running this same kind of multiple-choice test on real-world facts with audiences everywhere: students, teachers, executives, journalists. Progress Tab’s quiz applies that same test to a fresh set of questions, so a class can see the pattern in itself rather than read about it secondhand.
Try it with your own class
Open the quiz, project it, and let the class guess before you reveal. It takes about ten minutes end to end.
