Beyond ranking: exploring relative preferences in P/RRA

This paper argues in favour of moving beyond simple preference ranking in P/RRA as conventional methods produce limited data which is often misinterpreted. While ranking enables participants to define their own criteria for discriminating between items, it does not give an overall preference order because different items may have different weightings, so simple adding up would give misleading results. Asking participants to list items subjectively from best to worst overcomes this but still leaves the difficulty of interpreting the gap between ranks.
