I am planning to conduct a Focus group for car navigation devices in coming weeks.
Initially, I was recruiting mixed gender participants in each session.
I am slightly worried that;
Males might be more dominant in the conversation as they have more knowledge about the car navigational systems and in general they are more tech savvy.
Females might not be able to express themselves in front of male participants.
I think that I should have separate sessions for males and females to get most out of the study.
What are the negatives & positives for mixed and single sex, groups?
