4.2.2.3.3  Friedman Test for the Blank Filling Data - Group 3 
 
The results of the Friedman test for the blank filling data for Group 3 
show a significant difference in the students' mean accuracy of response to the 
13 types of collocation in the blank filling data (Friedman c
2
 (12, N = 13) = 
191.452, p = .0001).  Nemenyi's multiple comparisons tests based on Friedman's 
rank sums were performed on the data.  The results of these tests are 
summarised below in Table 41.  According to the results, Type 33. Verb Adverb 
with the highest mean rank (i.e. most accurately answered), and Type 28. Verb 
Noun (eradication) with the lowest mean rank (i.e. least accurately answered), 
are significantly different to all the other types of collocation.
