Answer:
qualitative
Step-by-step explanation:
In this case, the researcher is trying to obtain qualitative data from the customers to try to determine if they are satisfied with the product or not. Qualitative data is non-numerical, it will not tell us if our product is the best, but it will tell us how our customers view or feel about our product. Qualitative data is information about the characteristics of something, its qualities, and it is not something that you can assign a numerical value.
