Rounded Up, Fully Booked

A Regression-Discontinuity Test of a Trades-Booking App's Half-Star Rounding Line

A research poster from the School of Continuous Improvement exploits the naturally occurring half-star rounding line on a trades-booking app's displayed rating, finding that providers whose raw score lands just above the line draw substantially more weekly bookings than statistically identical providers just below it, while an independent completion-rate record passes through the same line unmoved.
