Problem 1: Using the research topic "Impact of Food Quality and Variety in Customer Satisfaction, A study of Buffet Restaurant in Macao". Please provide a sample descriptive analysis of the data to understand the basic features of the data, such as the mean, median, mode, and standard deviation.
Problem 2: Provide a sample factor analysis (statistical technique) which will identify the underlying dimensions of food quality and variety influencing customer satisfaction. Factor analysis is a statistical technique used to reduce a large number of variables into a smaller number of factors. This technique will help identify the key aspects of food quality and variety that are most important to customers.
Problem 3: Provide a sample multiple regression analysis that will determine the relationship between these factors and customer satisfaction. Multiple regression analysis is a statistical technique used to understand the relationship between one dependent variable (in this case, customer satisfaction) and several independent variables (in this case, the factors identified through factor analysis). This analysis will provide insights into how much each factor contributes to customer satisfaction, allowing the restaurant's management to prioritize their efforts accordingly.
