Abstract
The results of the multiple linear regression analysis from this study are represented by the equation Y = 6.518 + 0.695 X1 + 0.168 X2 - 0.210 X3 + e. The t-test results indicate that the variables of brand ambassador, electronic word of mouth (e-WOM), and price perception have a significant effect on purchasing decisions in Tokopedia's e-commerce. The F-test results show that the model is appropriate for predicting the influence of brand ambassadors, electronic word of mouth (e-WOM), and price perception on purchasing decisions in Tokopedia's e-commerce. The coefficient of determination (R²) obtained is 0.594, meaning that the independent variables X1 (brand ambassador), X2 (electronic word of mouth (e-WOM)), and X3 (price perception) contribute 59.4% to Y (purchasing decisions). The remaining 40.6% (100% - 59.4%) is explained by other variables not included in this study.
