A new Slop University signage poster reports a pre-registered trial of assigned star averages on suburban playground listings, and describes the fixed figure now printed on the University's campus courtyard listings.
A new research poster sets playground listings against their stars for eighteen Saturdays, and the University has chosen a single figure for its courtyards.
For eighteen Saturdays, the star average on a playground’s listing was a matter for a trial rather than for its visitors. A research poster from the School of Continuous Improvement, published today for the University’s bus-stop and campus display panels, reports what the families did about it, and the University has since settled on one figure for its own courtyards.
We went in expecting to learn something about stars and came away having learned how little the playground asks of us.

Dr Ntuli led the work with Senior Lecturer Renke Sabel and Lecturer Marit Osayande. The team allocated each of forty-two suburban playgrounds, by lot, to one of three displayed averages, and arranged for a volunteer at every gate to count the families arriving on Saturday mornings. The counters were not told which figure their playground carried. A margin for sameness was lodged before the first Saturday, and the three groups of playgrounds sat well inside it.
The University’s campus courtyards will now each carry a fixed average of 4.4 on their listings, and review collection for them has been retired. The figure is set once, at installation, and is held for the life of the listing, including at any courtyard whose visitors would like to leave a review. Lecturer Osayande said the counters “kept their clickers steady from the first Saturday to the last, and the team is glad of it.”
