The article "Can We Really Walk Straight?" (American Journal of Physical Anthropology [1992]: 19-27) reported on an experiment in which each of 20 healthy men was asked to walk as straight as possible to a target 60 m away at normal speed. Consider the following observations on cadence (number of strides per second):

0.95 0.85 0.92 1.95 0.93 1.86 1.00
0.92 0.85 0.81 0.78 0.93 0.93 1.05
0.93 1.06 1.06 0.96 0.81 0.96

Construct a dotplot for the cadence data. Do any data values stand out as being unusual?
