Note that points, i.e., statements, sorted more often together appear closer to each other, and statements never/rarely sorted together appear widely separated; Arrows indicate a statement is reallocated by researchers, circles indicate a new cluster is created by researchers as a result of reallocation of statements; Cluster 1: I sit because it is the norm/I sit because I have to; Cluster 2: I sit because I want to make contact with my friends; Cluster 3: I sit because I can work/play better that way; Cluster 4: I sit because there is nobody to play (actively) with; Cluster 5: I sit because I’m tired, I want to relax, I want to rest; Cluster 6: I sit because the physical environment is not suitable; Cluster 7: I sit because seated activities are fun; Cluster 8: I sit because there is nothing to do.
