A researcher studied the effects of avatar customisation on feelings of social closeness during virtual reality interactions. There were 80 participants. The researcher assigned the first 40 people who signed up for the study to Group A and assigned the remaining 40 people to Group B.
The researcher asked participants in Group A to interact using highly customisable, expressive avatars over a one-week period.
The researcher asked participants in Group B, the control group, to interact using standard, non-customisable preset avatars over the same period.
One way of improving this study would be to use random allocation. Explain how random allocation could have been carried out in this study.
