Dr. Amalie

Dr. Amalie is a social psychologist who is interested in the effects of group size on efficiency and on the satisfaction of individual group members. In a study conducted by Dr. Amalie's research team, three different group sizes were used. Large groups had 20 people, medium groups had ten people, and small groups had four people. There were ten sessions run with each type of group, and each group contained different individuals, so the total number of groups was 30 and the total number of participants was 340. All participants were students at the school where Dr. Amalie works. The groups were told that they needed to come to agreement about which movie to select for an upcoming student movie night. The time that it took each group to come to a decision was recorded. Afterward, each subject was asked to rate his or her satisfaction with the group's decision (on a scale from 1 to 10, where 10 is totally satisfied).

The results were as follows:

Mean time required to come to an agreement (all differences are statistically significant):

Large groups: 20.7 minutes
Medium groups: 16.4 minutes
Small groups: 10.3 minutes

Mean satisfaction rating for individuals (all differences are statistically significant):

In large groups: 4.6
In medium groups: 7.5
In small groups: 8.8


There appears to be a correlation between efficiency and satisfaction, such that the less time required to make a decision, the greater the satisfaction of the group members. Which correlation coefficient would reflect this relationship?

In large groups: 4.6
In medium groups: 7.5
In small groups: 8.8


In this study, what is the operational definition of efficiency?


▸ difference between speed and satisfaction

▸ size of the group

▸ satisfaction ratings

▸ speed of decision

What is a measure of central tendency from this study?


▸ The satisfaction rating for large groups is 4.6.

▸ The difference in decision time between small groups and large groups is 10.4 minutes.

▸ There was a total of 340 participants in the study.

▸ The range of potential satisfaction scores is from 1 to 10.

In small groups: 8.8


What conclusion can you draw from the results of this study?


▸ Smaller groups are more likely to be influenced by the opinion of one individual.

▸ Group size is confounded with satisfaction ratings.

▸ Medium-sized groups have only a moderate amount of disagreement.

▸ Larger groups take longer to come to a decision.
