Chapter 1 the study of collocations

4.2.2  Hypothesis 2: There are patterns in the development of collocational 
knowledge within  proficiency groups 
 
To address Hypothesis 2 and examine the extent of the within-group 
differences in the use and knowledge of collocations, non-parametric Friedman 
repeated measures tests were used, followed by post-hoc Nemenyi's multiple 
comparisons procedures.  Implicational scaling for each of the three groups in 
each of the three sets of data was then performed.  Results of the analyses are 
reported below.
