The background of the study is the importance of vocabulary as one of language knowledge that should be mastered by the students in learning English. One of strategies to master vocabulary is using English movie. English movie is an audio visual medium giving students a chance to expand their ability and to develop their English skill. When students see an object or an action, their curiosity to know the vocabulary may be increased. When the vocabulary is discovered, it is learned very fast. When the activity has been done by the students continually, it will influence their vocabulary power.
The objective of this study was to respond the question ofhow much the influence of students’ frequency of watching English movies to their vocabulary power at Eleventh grade of Language study program of MA NU Banat Kudus in the academic year of 2012/2013 is.
This study used a quantitative approach with one predictor regression analysis. Regression analysis was used to investigate whether the raising of variable dependent could be influenced by the raising of variable independent. It was conducted at Eleventh grade students in Language study program of MA NU Banat Kudus in the academic year of 2012/2013. The total of subjectwere 45 students. The data were collected by questionnaire and test.
The result of this study showed that the correlationwasrxy:0. 814, so the determination of index correlation was r2 (0. 814)2 = 0. 663.It meant that the influence of variable X (the frequency of watching English movies) to variable Y (students’ vocabulary power) was 66. 3%. The regression similarity was Y = 0.777X + 7. 1493926164 so, it could be predictedif variable X increase 1 value, so variable Y will increase 0. 777 values and the result of regression analysis was Freg= 84. 70. In other word, it could be concluded that there was significant influence of the frequency of watching English movies to students’ vocabulary power. It was shown by Freg= 84. 70 >Ftable for significant level 5% = 4. 07. Therefore, Ha: there was influence of frequency of watching English movies was accepted, and Hi: there was no influence of frequency of watching English movies was denied.
