Multiple Choice

When the usual statistical procedures developed for group designs are to be applied to data from single-subject designs, the most straightforward approach is to use the:

A) between-subjects differences to estimate error variance.
B) multiple observations taken within a treatment to provide an estimate of uncontrolled error variance.
C) multiple observations taken between treatments to provide an estimate of uncontrolled error variance.
D) between-subjects differences to estimate error variance and the multiple observations taken within a treatment to provide an estimate of uncontrolled error variance.
