Influence of Various Factors on Exam Scores of High School Students

Trabalho em grupo sobre pesquisa e análise de marcas de suco de caixinha (sabor laranja).

This case study examines the impact of introducing a new payment method, "ControvPay," on customer perceptions. While the addition was anticipated to enhance convenience, it also risked provoking negative reactions due to ethical controversies associated with the provider. To evaluate this trade-off, we conducted an experimental study measuring key metrics: * Perceived Ease of Use. * Perceived Corporate Social Responsibility. * Purchase Intention. * Customer Loyalty. * Payment Method Adoption. The analytical approach encompasses: * Data simulation and cleaning. * Reliability analysis. * Exploratory analysis with descriptive statistics and visualizations. * Balance checks using inferential tests (chi-square, t-test, ANOVA, correlations). * Comparative analyses with factorial ANOVA and ANCOVA models. * Sensitivity analyses with Bayesian modeling. * Mediation Analyses. * Simulation-based predictions. Although inspired by a real-world business challenge, the results presented here are simulated to ensure confidentiality.
