57.222%; (3) students’ reading comprehension skill was 71.250%; (4) there is a
positive significant correlation between student’s reading comprehension skill and
vocabulary mastery with the coefficient correlation (rx1y) 0.449, and the
coefficient significance (to) 2.722 > t-count 2.030; (5) there is a positive
correlation between students reading comprehension skills and grammar mastery
with the coefficient correlation (rx2y) 0.441, and the coefficient significance (to)
4.661 > t-count 2.030; and (6) there is a significant correlation between
