Cluster 1, n = 69. Cluster 2, n = 79. Cluster 3 exhibited stable preferences across all features and thus was excluded from these analyses. An FDR correction for 19 outcomes was applied to both between and within-subjects tests. Degrees of freedom are (1, 147) for all between-subject F tests. Significant between-subject tests following FDR correction are bolded. Superscript + and – indicate features perceived as more (+) or less (−) useful relative to each overall cluster average at the FDR P < .05 level.
