Abstract

ANNISA UL HASANAH AZMI. The Correlation Between Reference Group And Quality of Product With Purchase Decision iPhone in the Study Program of Commerce Education Student Faculty of Economics in State University of Jakarta. Study Program of Commerce Education, Faculty of Economics State University of Jakarta. This research was conducted in the Study Program of Commerce Education Student Faculty of Economics in State University of Jakarta, for four months, starting from March 2017 to June 2017. The purpose of this study is to determine correlation between reference group with purchase decision and correlation between quality of product with purchase decision iPhone in the Study Program of Commerce Education Student Faculty of Economics in State University of Jakarta. The research method used is survey method with the correlational approach, population used are all Commerce Education Student Faculty of Economics in State University of Jakarta who ever bought iPhone. The sampling technique used technique of purposive sampling as many as 70 people. The resulting regression equation is Ŷ = 31.97 + 0,65X 1 and Ŷ = 33.38 + 0,65X2. Test requirements analysis that estimates the error normality test regression of Y on X with test Lilliefors produce Lcount = 0,1040 for Y on X1 and Lcount = 0,1020 for Y on X2, while Ltable for n =70 at 0,05 significant level is 0,1058. Because Lcount < Ltable the estimated error of Y over X normally distribution. Testing Linearity of regression produces Fcount < Ftable is 1,45 < 1,76 for X1 and 1,04 < 1,80 for X2, so it is concluded that the linear equation regression. Hypothesis testing from the significance regression produces Fcount > Ftable which,80,35 > 3,98 for X1 and 89,07 < 3,98, meaning that the regression equation is significant. Correlation coefficient of Pearson Product moment generating rxy = 0,736 for X1 and rxy = 0,753 for X2, than perfomed the test significance correlation coefficient using t test and the resulting tcount > ttable, tcount = 8,964 for X1 and tcount = 9,438 for X2 and ttable = 1,67. It can conclude that the correlation coefficient rxy = 0,736 for X1 and rxy = 0,753 for X2 is positive and significant. The coefficient of determination obtain for is 54,16% which show that 54,16% of the variant of purchase decision is determined by reference group and 56,71% which show that 56,71% of the variant of purchase decision is determined by quality of product.
