ABSTRACT Foni Trisia, 2318070. The Correlation Between Vocabulary Mastery and Their Translation Ability at the 4th Semester Students of English Education Study Program in UIN Bukittinggi, A Thesis, State Islamic University of Sjech M Djamil Djambek Bukittinggi, 2025. This study aimed to investigate the correlation between vocabulary mastery and translation ability among fourth-semester students in the English Education Study Program at UIN Bukittinggi. The research was motivated by the critical role of vocabulary in language proficiency and the challenges students face in translation, often due to limited vocabulary. Specifically, it sought to determine if there was a significant relationship, the direction of that relationship (positive or negative), and the strength (magnitude) of the correlation. To achieve this aim, a quantitative correlational research design was employed. The population consisted of all 22 fourth-semester students enrolled in the translation subject, and the entire population was used as the sample (total sampling). Data were collected using two instruments: a vocabulary test (assessing form, meaning, and use) and an English-to-Indonesian translation test (using a news article). The data were analyzed using descriptive statistics and the Pearson Product Moment Correlation, preceded by tests for normality (Shapiro-Wilk) and homogeneity (Levene's Test) to ensure the appropriateness of the parametric test. The findings revealed a significant, positive, and moderate correlation between vocabulary mastery and translation ability (r = 0.490, p = 0.039). This indicates that students with higher vocabulary mastery tended to have better translation skills, and vice versa. The correlation was statistically significant, leading to the rejection of the null hypothesis, and fell within the 'moderate' range according to established criteria. The study concluded that vocabulary mastery is a crucial, albeit not sole, factor influencing translation performance among these university-level English education students.
