Question

Does talking while walking slow you down? A study considered mean cadence (steps per minute) for subjects using no walking device, a standard walker, a rolling walker, and a guided walker. In addition, the cadence was measured when the subjects had to perform dual tasks. The second task was to respond vocally to a signal while walking. Cadence was measured for subjects who were just walking (using no device, a standard walker, a rolling walker, or a guided walker) and for subjects required to respond to a signal while walking.

(a) List the factors and the number of levels of each factor. (Select all that apply.)
