The mode of a numerical data set is the value that occurs most frequently in the set.
a. Determine the mode for the cadence data given in Exercise 73.
b. For a categorical sample, how would you define the modal category?
In Exercise 73
The article "Can We Really Walk Straight?" (Amer. J. 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.
