4.2.2.3.2  Friedman Test for the Blank Filling Data - Group 2 
 
The results of the Friedman test for the blank filling data for Group 2 
show a significant difference in the students' mean accuracy of response to the 
12 types of collocation in the blank filling data (Friedman c
2
 (11, N = 12) = 
202.339, p = .0001).  Nemenyi's multiple comparisons tests based on the 
Friedman's rank sums were performed on the data.  The results of these tests 
are summarised below in Table 40.  According to the results of the post-hoc 
analysis, Type 4. Prep Noun with the highest mean rank (i.e. most accurately 
answered) and Type 33. Verb Adverb with the lowest mean rank (i.e. least 
accurately answered) are the ones that show significant differences to most of 
the other collocation types.
