Could you build this?

Yes It is a simple interactive web quiz evaluating numerical confidence intervals based on a classic Jeff Atwood blog post.

Discussion

9 comments analyzed.

Concerns raised: Scoring system marks close estimates wrong, treats as trivia rather than estimation skill, Allows gaming the system with extreme ranges (0 to 10^18) to get credit, Unit confusion between raw numbers and billions, Mobile UX: units not visible without scrolling

Feature requests: Show how far off estimates were (order of magnitude), Measure accuracy as mean percent difference instead of right/wrong binary, Add decimal separators to number input boxes, Display units at top of questions or in input boxes, Use slider interface instead of text input for range selection
