The result shows that the coefficient between variable X and variable Y is rxy = 0.604. The criteria of correlation between two variables among 0.600 – 0.800 shows a highly correlation. The significant level at 5% is rtable = 0.361, rxy > rtable (0.604 > 0.361). The significant level at 1 % is rtable = 0.463, rxy > rtable (0.604 > 0.463). The result of the analyses shows that there is a significant correlation between vocabulary mastery and writing ability of third semester students of English Study Program of Nusa Cendana University.
