I have data collected with 5 Likert Scale Questionnaire to establish factors influencing customer satisfaction using online banking. The factors included Credibility, Efficiency, Ease of Use, Security, Problem Handling and Product/Service Portfolio. A total of 6 independent variables. In this case, what is the best hypothesis test recommended? Can I still perform Multi Regression using Customer Satisfaction as Dependent Variable? Because my questionnaire does not measure customer satisfaction. Therefore, I don't have any data available for customer satisfaction. What is the best analysis to perform and interpret this data? After performing the normality test, all my 6 variables are not normally distributed.
