Abstract
The objective of this study is to comprehensively analyze the prototypical research-oriented lexical bundle in a quantitative research article to see whether the sub-design of quantitative research i.e., correlational, and experimental studies have any differences regarding the usage of PROLBS. Based on these objectives the study selected 2576 total research articles from 11 subjects within 5 major disciplines. The distribution of the data is based on research design and journal ranking and then data is divided into article sections. The AntConc software was used for the retrieval of the frequency of the LBs
The study examined the impact of quantitative research sub-design correlational and experimental studies on the distribution of five sub-categories of prototypical research-oriented lexical bundles PROC_LBs, LOC_LBs, and GRP_LBs, QUAN_LBs and DESC_LBs in articles using the Kruskal-Walis H Tes. One Kruskal-Wallis H tests were conducted to find out the differences among quantitative research sub-designs with respect to the Prototypical research-oriented lexical bundle. The analysis showed that publications reporting on experimental research had a higher mean rank for PROC_LBs, LOC_LBs, and GRP_LBs, which reflects the articles' attention to methodology, causation, and empirical rigor. However, the mean rank for QUAN_LBs and DESC_LBs was greater for correlational research articles than for experimental research articles. This may be because correlational studies place more weight on exploring correlations between variables. Thus, this research can help second-language writers by pointing them in the direction of discipline- and genre-specific lexical bundles within quantitative research. Teachers can use this information to create lessons that are more specific to their student's needs, better preparing them for the varied demands of various research methods and academic fields.
