Answer:
C) quantitative research
Step-by-step explanation:
Quantitative researches focus on mathematical and statistical data analysis. Generally quantitative marketing researches are based on polls, surveys, or online questionnaires. E.g. a customer satisfaction survey that lists options 1-5, where 5 is very satisfied and 1 is very unsatisfied. The researchers will gather the information and obtain the survey mean and normal distribution.
In this case, Berne Retail plans to carry on a survey to determine the purchasing patterns of their customers, and they are going to do it using a statistical distribution. Once the most popular brands are determined, the store will focus on selling them while leaving underperforming brands behind.
