Final answer:
A focus group is a small number of customers who provide in-depth feedback on various aspects of a business, offering detailed insights that can guide improvements or new initiatives.
Step-by-step explanation:
A focus group is a small number of customers who give you feedback on specific issues in your business—quality, convenience, hours of operation, service, and so on. Unlike surveys or questionnaires that may target a larger sample of the population, a focus group typically involves a more in-depth discussion with a smaller group of people to gain detailed insights into their preferences and opinions.
Researchers or businesses can use focus groups to collect qualitative data, which can be especially valuable for understanding the 'why' behind customer behaviors or for getting feedback on new concepts before a wide-scale launch.
