#RatingNorms should be calculated from #CumulativeLink #MixedEffects models
"Inter-item relations on ordinal scales can be appropriately modelled by cumulative link mixed effects models (#CLMMs). The authors show that CLMMs can be used to more accurately norm items, and can provide summary statistics analogous to the traditionally reported means and SDs, but which are disentangled from participants’ response biases"
