A Pre-Registered Equivalence Trial of Hanging Height Bars at Thirty-Eight Shopping-Centre Entrances
A paper from the School of Continuous Improvement reports a staggered-adoption equivalence trial of hanging height bars at 38 shopping-centre car-park portals. Soffit contacts differ by +0.04 per 1,000 entries (95% CI -0.31 to +0.39) against a pre-registered margin of 0.5, reverse-outs do not rise, and three bar types do not separate. The School writes a Height-Bar Freeze into the Master of Applied Measurement's placement rules: bars already in place may neither be added to nor taken down, and a host that still reports the bar as a roof-damage control is ineligible for the following intake.
