Five distribution-free alternatives to parametric analysis of covariance (ANCOVA) are presented and demonstrated using a specific data example. The procedures considered are those suggested by Quade (1967); Puri and Sen (1969); McSweeney and Porter (1971); Burnett and Barr (1978); and Shirley (1981). The results of simulation studies investigating…

Research over the past 15 years concerning parametric and nonparametric statistics and 10 recently developed nonparametric techniques for testing interactions in experimental design are reviewed. The new nonparametric techniques are robust, powerful, versatile, and easy to compute. A fabricated dataset is used to illustrate the technique. (TJH)

Includes seven articles focusing on various research techniques important for counselor use including: (1) multivariate analyses; (2) time-series designs; (3) nonparametric statistics; (4) value orientation analysis; and (5) path analysis. Also discussed are models of developmental research and techniques for simultaneous inference. (RC)
