A Correlation Between Vocabulary Mastery, Grammatical Competence and Reading Ability

Abstract

The objectives of the study are to find out whether or not there is a correlation between (1) vocabulary mastery and reading ability (2) grammatical competence and reading ability (3) vocabulary mastery and grammatical competence simultaneously and reading ability. The correlation method is used in this research. The sample of this research is 30 students from Class B which was taken randomly using simple random sampling. The data of vocabulary mastery, grammatical competence, and reading ability in this research were collected using test. The data are then being analyzed using simple correlation and multiple linear regressions. The research findings show that (1) there is significant positive correlation between the students‟ vocabulary mastery and reading ability with the coefficient of correlation (rx₁y) 0.5469 and the significance of coefficient of correlation (t_o) 3.4571 > t table 1.70 (2) there is significant positive correlation between the students‟ grammatical competence and reading ability with the coefficient of correlation (rx₂y) 0.5377 and the significance of coefficient of correlation (t_o) 3.3753 > t table 1.70 and (3) there is positive significant correlation between the students‟ vocabulary mastery and grammatical competence simultaneously and reading ability with F_o (8.22) > F_t(3.35). It can be concluded that reading ability will simultaneously follow the increase and decrease of vocabulary mastery and grammatical competence.
