Boxplot of the evaluator ranks across ten cluster solutions in the T. baccata dataset: 1 initial algorithm, 2 FPFI and 3, 4, 5, 6, 7, 8, 9, and 10 are IndVal, 4 Indval, 5 IndVal, 6 Indval, 7 r, 8 r, 9 r based, 10 r based TFVI models. These are partitioned in three definite parts including (a) initial with FPFI solutions, (b) IndVal-based solutions, and (c) phi-based solutions. The box extends from the first quartile to the third quartile. The crossed line in the center of the box is the median. Each boxplot is based on three ranks, corresponding to the three initial classifications. The best solution (lowest average rank) is indicated using a checkmark symbol
