Abstract
In this study, the exact distributions of the Kao and Chakraborti's
Statistics for comparing treatments with a control in a randomized
complete block design are obtained. Some exact critical values found
from this distribution are also given. A great many differences for this
statistics have been found between the cumulative probability values
by the usual approach proposed by Kao and Chakraborti and those of
the exact distributions, even when the sample size is inadequate.
