Focus group participants can be monitored in real time, both on an individual and aggregate basis. It is possible to determine how engaged the group is in real time and whether individuals are “tuning out” or engaging – even if they display no outward signs. Common stimuli (e.g., products, advertising, media, etc.) can be evaluated. Responses to stimuli can be aggregated across multiple groups to achieve quantitative sample sizes (~20 people) through event marks.
