Final answer:
Online focus groups offer convenience, cost-effectiveness, and access to a diverse group of participants. However, one disadvantage is potential lack of respondent honesty.
Step-by-step explanation:
The advantages of online focus groups include convenience, cost-effectiveness, and the ability to reach a diverse group of participants. However, one disadvantage of online focus groups is a potential lack of respondent honesty. In face-to-face focus groups, participants may feel more comfortable sharing their opinions and ideas because they can directly interact with the moderator and other participants. Online anonymity and the absence of non-verbal cues may reduce the level of trust and open communication in online focus groups.
