The Relationship Between Vocabulary Depth and Argumentative Essay Writing Proficiency Among IELTS Test Takers in Pakistan

The main object of this correlational study was to determine the relationship between vocabulary depth and argumentative essay writing proficiency among Pakistani IELTS test takers. Students with greater vocabulary knowledge and discourse expertise would produce texts of higher quality as compared to students with less of these skills. For this purpose, it manipulated three instruments for collecting the required data: a prompt for writing an argumentative essay, an IELTS band descriptor for scoring writing tasks, and the Word Association Test (WAT) for assessing vocabulary depth knowledge. It involved 129 Pakistani IELTS test-takers as its population. The sample comprised 42 females and 87 male participants. The data was analysed using SPSS version 23. Pearson's product moment analysis was used to determine the relationship between both continuous variables (vocabulary depth and argumentative essay writing), and the results revealed a negative or weak relationship between vocabulary depth and IELTS essay band scores (r = -.032, p =.721). The current findings concluded that there was no statistically significant correlation between both variables. Furthermore, this research study would have certain suggestions for teachers, test designers, and material originators on how to incorporate the dimension of word associations into the creation of word knowledge. It would have some pedagogical implications and instructions for increasing linguistic aptitude levels, which would be useful in academic institutions, language assessment, and language teaching and learning centres such as IELTS training centers.
