Chapter 1 the study of collocations

ii) Analysis for Hypothesis 2 
 
 
To address Hypothesis 2, that there are patterns of development in the 
acquisition of collocations within proficiency levels, non-parametric Friedman 
repeated measures tests were performed on each group for each set of data, i.e. 
three Friedman tests per each set of data.  Friedman repeated measures test is 
the non-parametric equivalent for ANOVA repeated measures test.  These tests 
were followed by Nemenyi's multiple comparisons tests based on the Friedman 
rank sums.  The analysis for Hypothesis 2 also includes those collocation types 
that were not repeated across groups. 
 
For the free production essay data, separate repeated measures 
Friedman tests were performed for each group on the tokens for each of the 37 
types of collocation found in the students' essays, followed by Nemenyi's 
multiple comparison procedures.  Implicational scaling analyses using the 
frequency data for each group were also performed and the Guttman's 
coefficients of reproducibility and scalability were calculated.

For the cued production translation data, separate repeated measures 
Friedman tests were performed for each group.  There were 8 types of 
collocation for Group 1, 6 types for Group 2, and 7 types for Group 3.  These 
tests were followed by Nemenyi's multiple comparisons procedures.  
Implicational scaling analyses using the frequency data for each group were 
also performed and the Guttman's coefficients of reproducibility and scalability 
were calculated. 
 
For the cued production blank-filling data, separate repeated measures 
Friedman tests were performed for each group.  There were 14 types of 
collocation for Group 1, 12 types for Group 2, and 13 types for Group 3.  These 
tests were followed by Nemenyi's multiple comparisons procedures.  
Implicational scaling analyses using the frequency data for each group were 
also performed and the Guttman's coefficients of reproducibility and scalability 
were calculated. 
 
The following chapter presents the results of the analyses.
