Although both groups had a mean rating of neutral, the standard deviations tell a great deal here. With a standard deviation of .02, you know that the scores do not vary much at all. That is, most of the group have ratings very close to 5. With a standard deviation of 3.42, the story is much different. This group has ratings that deviate a great deal from 5, which indicates that there are many different and extreme positions in this group. Group B would most certainly have more lively discussions in this situation.
