• The distribution is not symmetric. There is a cluster from 23-27 and from 29-31, and a peak at 27.  There's a gap between 20 and 23.  There are no outliers.
• The distribution is not symmetric.  There is no cluster.  There is at peak at 24 and 27.  There's a gap from 23-27.  The outlier is 20.
• The distribution is symmetric.  There is a clus from 29-32 and a peak at 24.  Theris a gap between 20 and 23.  There are no outliers.
