Nilai koefisien determinasi (R²) sebesar 0,231 menunjukkan bahwa Social Influence mampu menjelaskan 23,1% variasi Keputusan Pembelian, sedangkan sisanya dipengaruhi oleh faktor lain di luar model penelitian. Hasil uji mean menunjukkan bahwa Social Influence dan keputusan pembelian sama-sama berada pada kategori tinggi, dengan mean empirik masing-masing 82,74 (hipotetik 65) dan 91,92 (hipotetik 75). This study aimed to examine the effect of Social Influence on purchase decisions of Skintific products among female students of the Faculty of Psychology, Universitas Medan Area. The research hypothesis stated that social influence has a significant effect on purchase decisions of Skintific products among students of the Faculty of Psychology, Universitas Medan Area. The study employed a quantitative approach with a population of 316 female students, from which 118 respondents were selected using purposive sampling. Data were collected using two psychological scales: a social influence scale and a purchase decision scale. Data analysis was conducted using SPSS. The results indicated that social influence has a positive and significant effect on purchase decisions. The regression equation obtained was Y = 11.255 + 1.011X, with a significance value of 0.000 (p < 0.01). The coefficient of determination (R² = 0.231) showed that social influence explains 23.1% of the variance in purchase decisions, while the remaining variance is influenced by other factors outside the research model. The mean test results also showed that both social influence and purchase decisions were in the high category, with empirical means of 82.74 (hypothetical mean = 65) and 91.92 (hypothetical mean = 75), respectively. | en_US |
