A 2012 study of freely forming groups in bars all over Europe examined the natural behavior of groups. The researchers recorded the group size (number of individuals in the group) of all 501 groups in the study that were naturally laughing. The findings were displayed in the figure below. Number of groups 300 250 200 150 100 50 0 254 2 168 3 52 21 4 5 Laughter group size 6 6

The distribution of group size in this sample of naturally laughing groups is O clearly right-skewed O roughly symmetric clearly left-skewed clearly bimodal with O a mild outlier. an extreme outlier. O no outliers. The mean of this variable is less than the median. greater than the median. equal to the median. Can we conclude from these findings that, in European bars in 2012, smaller groups were more likely than larger groups to be naturally laughing? Explain your reasoning in one short sentence.
