A small GUI usability study was conducted at a local college by a friend and I was asked to help:
20 participants, 12 female 8 male, youngest 18 oldest 31
Live sessions of ubuntu spins were used (my suggestion as it runs better than VM's and we weren't allowed to modify boot partitions).
Participants were asked to perform 12 simple tasks in each DE (simple stuff like transferring files and starting firefox, etc), they were asked to classify from 1 to 10 (least to most favorable) the experience they had. This is the rounded average of those 20:
- Xubuntu 7
- Lubuntu 8
- Ubuntu 6
- Ubuntu gnome 2
