The objective of the research is to find out whether or not there is a significant relationship between students’ vocabulary mastery and students’ reading comprehension skill at 9th grade students of SMPN 1 Cileungsi Bogor in 2016/2017 academic year. This research used correlational method, which was held on January 23rd, 2017 until February 13th, 2017 at SMPN 1 Cileungsi Bogor. The populations of the research are all the 9th grade students of 4 regular classes in SMPN 1 Cileungsi Bogor, which are around 160 students. Then, the writer took 12 students for every class randomly as sample of the research. Afterward, the data was analyzed by using pre-requisite tests, they are normality test, homogeneity test, linearity test. The result of normality test was known L0 < Lt (0,111 < 0,128) for X variable and L0 < Lt (0,124 < 0,128) for Y Variable; thus, data are normally distributed. The result of homogeneity test was Fobserved < Ftable, (1,234 < 2,016); so both variances data are homogenous. The result of linierity test was Ῡ = 11,77 + 0,67X, it means both of the data are closed to the linear.
The result of the research shows that the coefficient correlation (r) is 0.746, while the the rtable is 0.284. Since robserved > rtable. Then, the writer calculated the robserved with t-test in order to know how far the significance. The result of t-test shows that tobserved > ttable (7.624 > 1.677), so it can be concluded that there is a significant relationship between students’ vocabulary mastery and students’ reading comprehension skill at the ninth grade students in SMPN 1 Cileungsi, Bogor.
Finally, it is expected that this research can be useful for the readers, especially the teachers to improve their students’ vocabulary mastery in order to make their reading comprehension better.
