The primary purpose of the present paper is to call attention to Hawkins’ (4) procedure for testing a sequence of observations for a shift in location. Such a procedure could have applicability for assessing change within a single subject. Monte Carlo results are provided which suggest that Hawkins’ procedure is robust with respect to moderate violations of its underlying assumptions of homogeneity of variance and normality. A hypothetical example is also discussed for illustrative purposes.
