Identification and Description of Homogeneous Subgroups within a Sample of Misarticulating Children A multivariate, hierarchical clustering procedure was used to identify homogeneous subgroups among 98 misarticulating children age eight years through nine years, six months. Clustering was based on 40 tests or measures of language, auditory processing, school achievement, oral structure, oral form recognition, and other phenomena. Clusters were described and then ...

A multivariate, hierarchical clustering procedure was used to identify homogeneous subgroups among 98 misarticulating children age eight years through nine years, six months. Clustering was based on 40 tests or measures of language, auditory processing, school achievement, oral structure, oral form recognition, and other phenomena. Clusters were described and then compared for performance on measures of articulation status and articulation improvement with training. Clusters were also derived from subsets of children who misarticulated only one sound, either /s/ or /r/. Also, the subset of children who misarticulated /s/ was compared with children who misarticulated /r/ for performance on the measures classified above. Few of the clusters identified differed in articulation status or improvement with training.
