The purpose of this study is to statistically verify that the HSK verb vocabulary grade is not suitable for Korean learners. For example, when targeting Korean learners, even if the verb vocabulary is at the same grade, there may be a difference in average scores between the vocabularies. On the contrary, although the series of the HSK verb vocabulary are different, we try to verify that the scores may be similar among the vocabulary types.
First, there was a statistically significant difference in scores for grade 5 ‘Chinese characters’ and grade 5 ‘nonequivalent word’, grade 5 ‘Equivalent’ and grade 5 ‘nonequivalent word’. There was a statistically significant difference between the grade 6 ‘Chinese characters’ and grade 6 ‘nonequivalent word’. It can be seen that the HSK verb vocabulary grade is not suitable for Korean learners.
Second, HSK grade 4 ‘Chinese characters’ and grade 6 ‘Chinese characters’, grade 5 ‘Chinese characters’ and grade 6 ‘Chinese characters’ had similar scores. There was a vocabulary with a similar score difference in the ‘Equivalent’ and ‘nonequivalent word’. The verb vocabulary is grade 4, grade 5, and grade 6, but the difference in grades is not significant.
In this study, it was verified whether the difficulty of grade 5 vocabularies could be made similar by adjusting the series of some vocabulary types related to grade 5. As a result, the scores of the grade 5 ‘Chinese characters’, the grade 5 ‘Equivalent’, and the grade 5 ‘nonequivalent word’ were similar for the grade 5 subjects.
