QUESTION 43

Your study will examine virtual teams over an extended period (at least several weeks). You understand that in any longitudinal study there is the possibility of subject attrition (e.g., members of the teams may drop the class and not be part of the team at the end of the study). Which technique, theoretically, best controls for attrition?

Permanently remove any team that loses a majority of its members during the course of the study.

Replace missing team members with new people who respond just like the missing members.

Whenever a team loses a member, randomly remove one member from every other team.

Do nothing. Simply report the losses then proceed as if no attrition had occurred.

QUESTION 44

The Dean wants to know why attrition is a problem. Which is the best answer?

Teams who lose members may be different from teams who do not (e.g., they may lose the weaker students and thus end up being “better” teams).

Teams who lose members contaminate measurement precision of the teams who do not lose members (e.g., smaller teams make it more difficult to assess larger teams).
