Which of the following factors contributes to increased order frequency at the pizzeria?

Increased order frequency at a pizzeria can be largely influenced by factors that attract and retain customers. The choice of student popularity highlights a critical demographic that often has specific needs and preferences, such as convenience and affordability, particularly in a college town or near universities. Students are likely to order frequently due to factors such as late-night cravings or social gatherings, which may lead to a higher volume of orders.

While discounts and promotions can attract customers and high customer satisfaction can lead to repeat business, these factors may not directly link to a specific demographic's ordering habits as clearly as student popularity does. Similarly, while a convenient location is important, it primarily affects accessibility rather than directly correlating to frequency of orders. The focus on a demographic that actively seeks out pizzeria options in a social and budget-conscious manner explains why student popularity is a strong contributor to increased order frequency.
