As illustrated in the graph, participation ranged from groups of 3 to 40 and recruited from 0 to 14 new users after inputs ranging from 5 to 45 hours. In the graph, the number of new users recruited for each workshop are illustrated by bubble size and label. It appears that, the larger the workshop, the lower the proportion of new user account as well as that the more hours invested, the more new user accounts were created. However, no conclusion can be drawn without additional observations.
