1.63 x and s are not enough. The mean X and
standard deviation s measure center and spread but
are not a complete description of a distribution. Data
sets with different shapes can have the same mean
and standard deviation. To demonstrate this fact, find
X and s for these two small data sets. Then make a
stemplot of each, and comment on the shape of each
distribution.
