Fig. 6. The relationship of the evaluation dimension to the five ecological measures and the two subjective descriptions provided by the regression tree analysis for participants who had a working association with coral reefs (A) and those who did not (B). The values of the predicted variables for the ecological measures provided on the tree are the percent cover and, for the perceptual meanings, the value from the component matrix. The regression tree analysis determined four groups of photographs (A, B, C, and D), and the mean evaluation score (E) for each group is provided.
