Team Building can be assessed quantitatively. The lower the team average score for a certain criterion, the more room for improvement. Individual team members can rank each criterion by a ranked perception scale of: $0=$ Completely False, $2=$ Somewhat False, $4=$ Somewhat True, and $6=$ Completely True. When asked to rank the organizational mission statement on clarity, a four$-$person team responded with the following dataset:

$6,6,4,4.$
