Observation would be the best method for Erica to collect this data because she can observe customers' behavior in the store, such as which types of products they pick up first and which areas of the store they spend the most time in. This method would provide Erica with accurate and detailed information about the customers' purchasing habits and the type of assistance they need while shopping.
