Abstract

One-way analysis of covariance is a popular and common statistical
method, wherein the equality of the means of several random variables which
have a linear relationship with a random mathematical variable, is tested. In
this study, a method is presented to improve the one-way analysis of covari-
ance when there is an uncertainty in accepting the statistical hypotheses. The
method deals with a fuzzy test statistic which is produced by a set of con dence
intervals. Finally an example is provided for illustration.
