Chapter 1 the study of collocations

 Type 
26. SVc - Results of the Kruskal-Wallis test for numbers of tokens 
of SVc collocations used in the subjects' essays shows a significant main effect 
for the factor Group (Kruskal-Wallis c
2
 (2, N = 275) = 41.535, p = .0001).  The 
table of means, Table 25, shows that the mean number of tokens of this type of 
collocation decreases as the proficiency level of the subjects increases.  The 
results of the post-hoc Dunn's multiple comparisons procedure show 
significant differences in numbers of tokens of this type of collocation between 
all groups (see Table 24).
